Welcome to the Doomsday Show where vile creatures emerge from the dungeon and life points don't matter!


Kiki-Jiki Pile #1 - Zealous Conscripts:

The goal is to rush to cast Grenzo, cast Doomsday, and win. We do these by casting Doomsday when Grenzo is in play, and you have + mana available.

With Grenzo in play, cast Doomsday for , leaving you with mana

Pile the following, from Top to Bottom: Recoup, Zealous Conscripts, Goblin Sledder, Kiki-Jiki, Mirror Breaker, Priest of Gix

Spend mana, activating Grenzo, to bring in Priest of Gix, and acquiring

Spend mana, activating Grenzo, to bring in Kiki-Jiki, Mirror Breaker, who will then activate making a copy of Priest of Gix, pooling

Spend mana, activating Grenzo, to bring in Goblin Sledder, who will sacrifice himself to add +1/+1 to Grenzo, leaving you with pooled

Spend mana, activating Grenzo, to bring in Zealous Conscripts, who will take control of Kiki-Jiki and untap him

Kiki-Jiki will then go infinite with Zealous, creating infinite tokens with haste, who attack and win.

Recoup is left on the pile as protection to recast Doomsday in case you are foiled the first time.

Kiki-Jiki Pile #2 - No Zealous Conscripts:

The goal is to rush to cast Grenzo, cast Doomsday, and win. We do these by casting Doomsday when Grenzo is in play, and you have + mana available.

With Grenzo in play, cast Doomsday for , leaving you with mana

Sacrifice Kiki-Jiki and Redcap to Skirk Prostpector, giving you

With Redcap's Persist trigger on the stack, activate Grenzo again with your remaining mana to bring in Metallic Mimic naming Goblin

This returns Murderous Redcap without any counters, allowing you to go infinite with Redcap being sacrificed to Skirk, while returning with no counters on due to Mimic. This creates an infinite loop of 2 damage dealt to a player, killing the table.

No Kiki-Jiki in Pile:

If Kiki-Jiki has been removed from the game, our pile changes. This pile will rush to cast Grenzo, cast Doomsday, and win. We do these by casting Doomsday when Grenzo is in play, and you have + mana available.

With Grenzo in play, cast Doomsday for , leaving you with mana

With Redcaps Persist trigger on the stack, activate Grenzo again with your remaining mana to bring in Metallic Mimic naming Goblin

This returns Murderous Redcap without any counters, allowing you to go infinite with Redcap being sacrificed to Skirk, while returning with no counters on due to Mimic. This creates an infinite loop of 2 damage dealt to a player, killing the table.

No Doomsday:

If Doomday is countered, your goal is to assemble the Murderous Redcap, Metallic Mimic, and one of our sacrifice outlets (Skirk Prospector, Mogg Raider).

With those pieces in play, and Mimic naming goblin, Redcap goes infinite damage with a sacrifice outlet.

Combos

Grenzo was chosen due to his immense synergy with Doomsday piles. - He acts as your catalyst to crack into your pile.

  • He places creatures directly onto the board, preventing interaction from counterspells.

  • His ability is stacked at instant speed.

  • His ability allows us to bypass cards with Rest in Peace and Leyline of the Void replacement effects. Due to the nature of the replacement effect, the card will be placed into exile, and drawn back out due to Grenzo's ability being indifferent to the final zone the card ends up in, caring only about the initial move from the library to a public zone.

The desire to play Grenzo Doomsday will depend a lot on what youre looking for in an EDH deck. If youre looking for a deck with endless backup plans, this might not be for you. If youre looking for a deck to impress your friends with your endless ability to chain spells, this might not be for you. If you want a deck that slows the game down to a crawl, or reanimates everything, wins with commander damage, or has gameplans so long and complicated youre positive your friends will never catch on, this deck might not be for you.

This deck is for people who;

  • Want a fast, efficient deck that consistently threatens a win between Turns 2-4
  • Want a deck with a straightforward wincon, but multiple angles to complete it
  • Want a deck with a straightforward backup wincon
  • Want a deck that utilizes your commander
  • Want a deck that can often get around instant speed interaction and most graveyard hate
  • Want a deck that plays out reliably and consistently
  • Want a deck that can play competitively at a price point cheaper than most semi-budget decks If these needs sound like your needs, then you may just have found the deck youre looking for.

The goal is to race your opponents to 5 mana, cast Grenzo, and use the wide tutor suite to find and cast Doomsday as quickly as possible. This occurs as early as turn 1, but is commonly played out on turn 3, (or turn 4 through hate.) If, for some reason you fail to succeed in casting Doomsday, your backup is to tutor or wheel into a Recoup effect (covered in a later section), or hardcast the Redcap Combo if Doomsday becomes exiled or grasped.

Because we are racing to acquire 5 mana, our ideal hand would include the following pieces: 2-3 Land (Multicolored or Swamp)

1-2 Artifact Ramp

1-2 Tutors (Instant speed is preferred, such as Vampiric Tutor)

1 Protection Spell (Counterspell prefered, such as Pyroblast)

1 Ritual Effect (Dark Ritual or Rite of Flame preferred)

An example T1 God-Hand would look something like;

Kiki-Jiki Pile #1 - Zealous Conscripts:

The goal is to rush to cast Grenzo, cast Doomsday, and win. We do these by casting Doomsday when Grenzo is in play, and you have + mana available.

With Grenzo in play, cast Doomsday for , leaving you with mana

Pile the following, from Top to Bottom: Victimize, Zealous Conscripts, Goblin Sledder, Kiki-Jiki, Mirror Breaker, Priest of Gix

Spend mana, activating Grenzo, to bring in Priest of Gix, and acquiring

Spend mana, activating Grenzo, to bring in Kiki-Jiki, Mirror Breaker, who will then activate making a copy of Priest of Gix, pooling

Spend mana, activating Grenzo, to bring in Goblin Sledder, who will sacrifice himself to add +1/+1 to Grenzo, leaving you with pooled

Spend mana, activating Grenzo, to bring in Zealous Conscripts, who will take control of Kiki-Jiki and untap him

Kiki-Jiki will then go infinite with Zealous, creating infinite tokens with haste, who attack and win.

Victimize is left on the pile as protection to return Kiki and Zealous the following turn (or if you have extra mana, the same turn) to proceed with the same combo.

Kiki-Jiki Pile #2 - No Zealous Conscripts:

The goal is to rush to cast Grenzo, cast Doomsday, and win. We do these by casting Doomsday when Grenzo is in play, and you have + mana available.

With Grenzo in play, cast Doomsday for , leaving you with mana

Sacrifice Kiki-Jiki and Redcap to Skirk Prostpector, giving you

With Redcap's Persist trigger on the stack, activate Grenzo again with your remaining mana to bring in Metallic Mimic naming Goblin

This returns Murderous Redcap without any counters, allowing you to go infinite with Redcap being sacrificed to Skirk, while returning with no counters on due to Mimic. This creates an infinite loop of 2 damage dealt to a player, killing the table.

No Kiki-Jiki in Pile:

If Kiki-Jiki has been removed from the game, our pile changes. This pile will rush to cast Grenzo, cast Doomsday, and win. We do these by casting Doomsday when Grenzo is in play, and you have + mana available.

With Grenzo in play, cast Doomsday for , leaving you with mana

With Redcaps Persist trigger on the stack, activate Grenzo again with your remaining mana to bring in Metallic Mimic naming Goblin

This returns Murderous Redcap without any counters, allowing you to go infinite with Redcap being sacrificed to Skirk, while returning with no counters on due to Mimic. This creates an infinite loop of 2 damage dealt to a player, killing the table.

No Doomsday:

If Doomday is countered, your goal is to assemble the Murderous Redcap, Metallic Mimic, and one of our sacrifice outlets (Skirk Prospector, Goblin Chirurgeon, Mogg Raider, Viscera Seer).

With those pieces in play, and Mimic naming goblin, Redcap goes infinite damage with a sacrifice outlet.

Rakdos colours make our land selections very obvious, we need as much black and red as possible, as fast as possible. For this, we run 30 lands, 1 more than the classic 29 land base thats become popular, simply because we often want to start with 3 lands in hand, or have enough to ensure we get more on wheels. Fetch Lands:

We run all 7 dual colour suitable fetch lands. It is important for this deck to open with as much colour variety as possible, allowing us access to both black and red to cast Grenzo, and enough black mana for Doomsday.

Fetch Targets:

These are the lands youll want to target with your fetches. Doing so ensures we have adequate coverage of our colour need to both cast Grenzo, as well as Doomsday the following turn.

  • Badlands
  • Blood Crypt Going Fast Lands

These lands are used due to their synergy with our Turn 3 win plan. While many decks may find them suboptimal, Grenzo requires a direct effort to maximize the speed of our available mana in the first three turns, because for Grenzo, there is not much a late game.

  • Peat Bog Utility Lands:

  • Cavern of Souls - Naming Goblin on Caverns allows us to jam Grenzo and most of the parts of our alternate wincons without having to worry about immediate counterspell interaction.

  • Lake of the Dead - The ability of this land allows us to play out Doomsday and the subsequent piles if we dont happen to draw suitable artifact ramp. Tapping a Swamp for B, then playing Lake and sacrificing that Swamp allows us to aquire BBBBB with simply two lands. Remembering 5 mana is all we need to Doomsday and win, Lake allows us to do that while fighting through land destruction and artifact hate.
  • Urborg, Tomb of Yawgmoth - Urborg allows us to ensure we hit our mandatory 3 swamps for Doomsday, and works to colour fix against possible land hate. It remains weak to Blood Moon effects, but can and will save you if someone happens to remove your black producing lands. The Rest of the Lands

The remainder of our lands are included to provide fast access to colours, untapped, on the turn we play the land. We run 10 basic Swamp and 1 Mountain to play around non-basic land destruction. 10 swamps gives us our best swamp-to-muck/filth ratio without cutting into our red production. Ideally 11 swamps would be included, but we've found that ideal muck lines were affecting our red consistency too greatly.

Grenzo runs as many usable tutors as possible in order to find Doomsday as quickly and efficiently as it can be in the early turns

  • Vampiric Tutor- This is what youre hoping for in your ideal hand, as for the low cost of a B and 2 life, Doomsday goes neatly to the top of your library.
  • Imperial Seal - The same as Vampiric Tutor.
  • Demonic Tutor - Puts the desired card directly in hand.
  • Diabolic Intent - Doomsday allows us to recur most of our creatures, so we can use them as pitch to Intent.
  • Dimir Machinations - This card is cast for its transmute cost, and allows the deck to find the majority of its main cards like Doomsday, Yawgmoth's Will, Toxic Deluge, etc
  • Gamble - This is your hailmary tutor! If you really want to go fast, this one will do it for you, but beware the chance to discard your own wincon. Use it on turn 1 or 2, or freely after wheeling or ad-naus.
  • Grim Tutor - A little costly, but added for the redundancy. This costs 3 to get your necessary card, and improves our ability to find a tutor on our draw or opening hand.
  • Plunge into Darkness - Not really a tutor, but we're going to use it as close to one as we can when all we need is Doomsday or a piece of ramp. Because this is risky in that it can exile combo pieces while hunting for an enabler, I have found that I often will stop my plunge at 8-10 cards, rarely going more than that, or you risk losing a piece from every combo.

The primary benefit of playing Grenzo Doomsday is the speed it brings to the table. Artifact ramp assures we get to cast our required spells as fast and efficiently as possible.

Colour Fixers

Colour fixing mana rocks ensure we have the proper colours to cast the spells regardless of our drawn land, while at the same time, being played for low costs so that we can play them early and cast more spells faster.

The following mana rocks are used to create and expand our colour availability for minimal initial cost.

  • Chrome Mox

  • Mox Opal

  • Fellwar Stone

  • Lotus Petal

  • Mox Diamond

  • Springleaf Drum

  • Rakdos Signet

  • Talisman of Indulgence

  • Jeweled Amulet

  • Chromatic Sphere

  • Chromatic Star

Colourless Ramp

Many of our spells and abilities come with a colourless cost, this is especially noticable with Grenzos activated ability. The follow mana artifacts produce maximum colourless mana for minimal cost. Remembering that a win only requires BBB+2, drawing into one of the follow mana rocks can promote the chance to combo out a full turn earlier than without them.

  • Mana Crypt

  • Mana Vault

  • Sol Ring

Doomsday Ramp

A single mana artifact, but a great one, LED allows us to play Doomsday directly on BBB, rather than acquiring the following 2 mana. While it forces a hand discard, the cards in your hand are not as important as the speed to with you can play through a Doomsday pile, and LED can able that as early as T1 or T2 depending on your board state.

  • Lion's Eye Diamond

Spell Ramp provides quick access to coloured mana, and can quickly speed our rate of tutoring and ramp, increasing the speed in which our deck can find and cast Grenzo and Doomsday.

Ritual Effects

  • Rite of Flame
  • Cabal Ritual
  • Dark Ritual
  • Desperate Ritual
  • Pyretic Ritual
  • Culling the Weak Lands Matter Ramp

  • Bubbling Muck

  • Rain of Filth Creature Ramp

  • Blood Pet - A great first turn ramp drop if there are no other 1 drops playable in hand. Simian Spirit Guide - Often useful as a way to go back to back swamps in your opening hand, so that Grenzo can be cast on curve.

  • Overeager Apprentice - BBB is life, and Apprentice provides.

There is always a chance that you just dont mulligan into a working opening hand, or your primary plan falls apart due to hate or stax. In these circumstances, we need to behave like other decks, and increase our draw to find the pieces we need manually.

Wheels

Quickly refill or replace the cards in your hand using beloved wheels!

  • Wheel of Fortune Filtering

Replace the cards you dont need at that time with better ones!

  • Scroll Rack
  • Sensei's Divining Top
  • Natural Drawing

Just get more cards!

  • Necropotence
  • Ad Nauseam

Sometimes, you just dont want other players cards on the board, so we run enough removal to take care of the pivotal stax, ramp, and other hate pieces that are preventing us from winning as efficiently as possible.

  • Pyroclasm

  • Shattering Spree
  • Toxic Deluge
  • Smelt
  • Chaos Warp
  • Dismember
  • Rakdos Charm
  • Slaughter Pact
  • Fire Covenant
  • Proactive and Reactive disruption are limited in Rakdos colours, but are important to have inside of Grenzo, as being impacted by removal or hate after Doomsday has been cast becomes particularly important

    Proactive Disruption

    Being able to look at and remove pesky interaction cards from our opponents hands prove a cheap way to get around counterspells and disruption in Rakdos colours.

    • Duress
    • Inquisition of Kozilek
    • Thoughtseize
    • Praetor's Grasp And while removing cards might not be enough, we slot the following to ensure our opponents struggle to interact with us as we Doomsday off;

    • Defense Grid

    • Overmaster Reactive Disruption

    Sometimes, the best way to prevent losing, is just a good old counterspell, we dont get access to many of them in Rakdos colours, but we do put a premium on what we can get.

    • Burnout
    • Pyroblast
    • Red Elemental Blast Graveyard Disruption

    With the rise of Thrasio's/X, Hulk Combo, and a resurgence of Midrange decks, graveyard disruption isn't something that needs to be heavily invested in, but you'll be happy you have it.

    • Rakdos Charm

    Replaying cards a second time can often mean the difference between recovering from an ill fated counterspell that catches your Doomsday, a boardwipe you couldnt stop, or just hate that gets you down.

    Use these cards to have a second chance (or a third, or fourth) at winning your game.

    • Recoup
    • Yawgmoth's Will

    Sadly, Grenzo doesn't offer you a ton of flex position with how all-in on the race the deck is! That said, there are certainly spots that allow some leeway specifically depending on what you need out of the deck!

    The cards below are often in flux, and many can be found overlapping with our "Testing Section" as these cards are continuously removed and re-added as we hunt down the perfection of Grenzo.

    • Burnout , Pyroblast, Red Elemental Blast

    These are the cards that certainly shouldnt remain in the deck if your meta happens to be Blue-Lite! Consider replacing them with hate directed towards your offending colours! - Toxic Deluge, Pyroclasm. Fire Convenant

    These can certainly be replaced/brought in based on your meta with alternative forms of removal. If no one in your pods plays more than 1 creature a game, no reason to hang onto boardwipes - Defense Grid, Conqueror's Flail

    A nice meta choice to play on your Doomsday turn to protect you from counterspells and removal, but certainly not necessary if those things just don't seem to be happening at your tables. - Night's Whisper, Dark Confidant

    If your meta is all-in race combo's there's no reason to include passive card draw. In these pods, you're going to win big or lose big, so the game won't continue long enough to need these. Consider dropping for more meta dependent cards. - Undying Evil

    Fantastic if your meta is heavy on instant speed destroy effects, but unhelpful if that removal is instant speed exile.

    Currently, the list below are the cards that are in the add/drop testing position for future changes.

    +Recoup, -Past in Flames

    +Undying Evil, -Winds of Change

    +Conqueror's Flail, -Phyrexian Arena

    +Blackcleave Cliffs, -Dragonskull Summit

    • Peat Bog , -Smoldering Marsh

    +Fire Covenant, -Terminate

    • Springleaf Drum , -Mox Opal

    +Blood Pet, -Viscera Seer

    +Simian Spirit Guide, -Whipflare

    • Overmaster , -Goblin Chirurgeon

    +Jeweled Amulet, -Victimize

    +Smelt, -Vandalblast

    +Swamp, -Blackcleave Cliffs

    +Culling the Weak, -Conqueror's Flail

    • Overeager Apprentice , -Dark Confidant

    +Diabolic Intent, -Night's Whisper

    +Tormod's Crypt, -Undying Evil

    +Mox Opal, -Faithless Looting

    +Chromatic Sphere, -Dark Petition

    +Chromatic Star, -Tormod's Crypt

    Like every deck, there are often cards and combos that do not appear in this list that are often used in others. Sometimes there are cards that exist that seem like a perfect fit, but then dont end up appearing. Here are some of the notable exclusions for Grenzo Doomsday

    Worldgorger Dragon + Animate Dead

    This combo is often found in many Rakdos shells, especially in Doomsday. It promotes a system of infinite mana, and then infinite activations of Grenzo to draw the entire deck out until a combo or win condition is found.

    It has been excluded from this deck with the discovered of the Metallic Mimic combo listed in the combo section above.

    The reasons for exclusion are thusly;

    The cards needed for assembly of Dragon combo are many and varied, 4-5 card for reanimation and setup, as well as the Dragon itself lead to having between 8-9 cards in the deck dedicated only to creating this combo, but adding no value to any other aspect of our primary gameplan

    The Mimic combo only requires 6 cards, those cards can be used individually as a natural cast combo, added to a Doomsday pile, and operate as a backup pile when Kiki-Jiki is removed from the game with little to no additional setup time.

    An ill-fated counterspell on Dragon Combo will end the game as quickly as it starts, and with the availability of disruption in EDH, it was more likely to happen than not.

    Yahenni's Expertise

    This card is often toted as being a suitable replacement for Toxic Deluge. At face value, it essentially reads Pay 1 extra mana, to add a -3/-3 boardwipe to your 3 cost spell. Its exclusion is for the following reasons;

    It costs an additional mana over Toxic Deluge, and 2 additional over our other board wipes.

    It requires that youre holding a 3 mana spell of value. If you are not, then youre either jamming a spell simply to play it, or youre not casting a spell, and instead playing 4 mana just to add a -3/-3

    Yaheenis cannot be altered lower or higher based on need. Deluge can be cast for 1 to sweep stax peices without harming Grenzo, and it can be cast for 4+ to hit other hate such as Loxodon Gatekeeper , or other high toughness threats like a cheated in Elesh Norn . Yaheeni does not provide that utility.

    Seething Song

    Seething Song is simply removed due to its high CMC cost and it's massive overproduction of Red mana, which is not heavily needed in this deck.

    Currently in the works are the following for this primer:

    • Matchups

    Currently these budget versions are experimental. Grenzo's reliance on finding and casting Doomsday as soon as possible does take a larger hit by losing tutors than most decks do. That in mind, for slower or budget metas, I submit to you the following for your consideration;

    $1000 Budget Version aka 50% off!

    $750 Budget Version - Still in testing, will be posted soon.

    This deck and primer would not have been possible without the following people paving the way, and working with me on constant, daily, discussion on each and every card in the deck;

    hellnoire - noire's original Grenzo list was the inspiration to take up Grenzo Doomsday as a serious cEDH deck. His knowledge and guidance during development are a testament to his long entrenched work on the deck

    xkyle813x - Kyle's ability to analyse cards, and his development of the Mimic Doomsday pile and combo was revolutionary to change the effective and efficient use of our card slots, and alternate win conditions

    Neunviertel - Neunviertel's willingness to tolerate my rambling thoughts, and help the group decipher between what is indeed a good idea, and a pipe dream, has steered me away from more mistakes than I care to count!

    /u/JustinTBSmash (Reddit) aka Mr.Skittles (cEDH Discord) - Justin has consistently spurred our industrious efforts with his near enyclopedic knowledge of every card that might be viable. Often first to the gate with new ideas and suggestions, his help has shaped this deck more than he'd care to admit!

    IustitiaRex - Rex's constant support, encouragement, discussion and collaboration have allowed this deck to advance to this point. While he might disagree on his level of contribution, I can assure you his keen insight has help immensely.

    Clay_Puppington Who's work brought this list to my attention originally. His support of the list has waned, but his contribution remains.

    Noobzaurs Who helped me make revisions to the list and encouraged me to pursue using Worldgorger Dragon shenanigans, opposed to conventional wisdom. I have since taken it out, but the shoutout remains

    SamsWrath for his input and continued development of the archetype. https://www.moxfield.com/decks/wqA4TxKgN0CJZoMzYnsg2Q
