Sideboard Staples
Blood Moon: One of the classic red sideboard cards. Generally, we board this in against Scapeshift decks, UWR control (Anything that runs Celestial Colonnade), and junk/jund decks. Blood Moon serves a specific purpose here, as not only does it shut down the opponent's main win con, it also stalls, allowing us to build up a board presence.
Combust
: One of the best cards we have access to against UWR control, twin, and delver/UR/x tempo. It basically allows us to remove any creature they play, for two mana, and they can't stop it. I like to run 2-3, but some metas force goblin decks to go all the way up to 4.
Dismember: The life tradeoff is miniscule compared to the upsides. This gets rid of Tarmogoyf, problem affinity cards, and any other creatures we don't like. Similar to above, I like 2-3, but occasionally you have to go up to 4.
Shattering Spree: Extremely good artifact removal, does a great job of removing problem affinity cards. The downside is that it's a sorcery, so it can't hit Inkmoth Nexus or
Blinkmoth Nexus
. That brings us to:
Smash to Smithereens
: Instant speed artifact removal with a bolt attached. This brings in the damage, as well as removing problem cards. I prefer a 2-2 split of this and Shattering Spree, but if there's more 8-rack in your meta, you could go 3-2, 3-1, 4-1, or 4-0. It's really up to you :)
Torpor Orb/Grafdigger's Cage: These were at their finest when pod was legal, but with the recent bannings, they have become a little lackluster. Torpor Orb does a great job at shutting down twin, but unless you expect a lot of twin, I'd stick to
Combust
.
Shatterstorm
/Vandalblast: Mass artifact removal. I'd only play these if you expect a lot of affinity. Vandalblast can function as spot artifact removal to, but don't underestimate the difference 1 mana can make. Also, Vandalblast can be hit by Inquisition of Kozilek, while
Shatterstorm
cannot.
Goblin Assault: One of the best budget options against UWR control. It is essentially a hard-to-remove Goblin Rabblemaster.
Sideboarding Strategies against Popular Decks
BG/x or Rock
This is one of your better matchups, as their deck is slow and clunky. Spot removal isn't particularly good against you, but make sure to hold a few things back in case they have a blowout. Your main strategy game one is flood the board as quickly as possible, while using Lightning Bolts! and goblin grenades to clear out their blockers. Cards to look out for include: Tarmogoyf, Courser of Kruphix, Slaughter Pact, Abrupt Decay and Phyrexian Obliterator. During sideboarding, you generally want to bring in your removal (not
Combust
), and your Blood Moons, if any. Then, use the same strategy as game one to slam them hard. Cards to watch out for post-sideboarding include: Damnation, Slaughter Pact, Drown in Sorrow, and Lingering Souls. Your best bet against a Lingering Souls is to get a successful Legion Loyalist on the field.
Scapeshift
This is a very easy matchup game one. You simply overwhelm them with sheer power, as their deck is designed to kill on turn 5-7. They run very few creatures, and don't maindeck a lot of removal. The only card to look out for in game one is
Cryptic Command. In sideboarding, you generally want to bring in
Blood Moon and any engines you may have (like
Goblin Assault). Generally, you want to play more conservatively in game 2, as they will have access to cards like
Engineered Explosives,
Anger of the Gods or
Chalice of the Void.
Burn
One of your better matchups. Just be as aggressive as you can, and you will probably win. In game two, they usually bring in
Dragon's Claw. This means you generally want to bring in half of your artifact disruption, as
Dragon's Claw is a great card against you. There isn't much to look out for, as their deck is very redundant.
Living End
See above, except you need to be more suicidal in your playstyle, as having a few goblins in your graveyard when they combo off is usually a great idea. If you sideboard more burn spells, bring those in.
UW/x Control
This is a tough matchup. You usually win 30-40% of the time. Game one, you want to be conservative, yet aggressive. Watch out for
Path to Exile,
Cryptic Command,
Mana Leak,
Restoration Angel and
Snapcaster Mage. You usually lose game one, as their deck maindecks mass removal. In game two, you want to bring in any engines you have, any removal you have, and any
Blood Moons you have. Game two/three, your primary strategy is to wear them down until you can slowly kill them with an engine card. Watch out for
Timely Reinforcements post board.
8-Rack
This is your most varying matchup. Some games they win, some games you win. Your goal in this match is to be as fast as possible. Burn is your best friend, as
Ensnaring Bridge shuts you down game one. Generally, you want to board in all your artifact hate, as
Ensnaring Bridge is amazing against you. If you have burn, board that in too. TIP: Once you have 3-4 lands out, hold the rest of your lands in your hand, as it can trick them into
Thoughtseize
ing into nothing. Basically
Shocking themselves. Also, it provides discard fodder to
Liliana of the Veil.
Gifts Ungiven
Board in all your burn, then just be as aggressive as possible against them. Your strength lies in applying enough pressure that they are forced to destroy your creatures instead of combo. In game one, watch out for
Elesh Norn, Grand Cenobite. If you run
Grafdigger's Cage, board them all in. I'd put the odds of winning at 25%.
Storm
This is a OK matchup. You generally want to aggro them out, forcing them to deal with your threats instead of you.
Grafdigger's Cage is your best sideboard card against them. There isn't much to say about this matchup, as it is relatively simple.
Affinity
Whoever's faster wins. Game one is usually 45-55%, and is very close. Board in all your artifact hate, as well as
Blood Moon to deal with their man-lands. Cards to watch out for in both rounds include:
Galvanic Blast and
Cranial Plating.
Merfolk
Oddly enough, the other tribal deck in modern is one of your easier matches. In general, you can put them on a back foot and stick them into sticky blocking situations with a combination of Legion Loyalist and bolt. For side boarding, bring in extra removal and maybe 1 or 2 artifact removal spells to deal with Aether Vial. The only time they usually get an edge on you is when they can power out 2 or more lords by turn 3.
ELDRAZI!!!
Since theres so many versions of eldrazi running around, Ill just say this: Its not good. Winnable, but not good. The hardest part of it is their Chalice of the Void on one as well as their massive guys. A few notes for you: Hold onto lands and Goblin Grenades until you can get the killing blow, because sometime its important to be able to knock out a Reality Smasher before it kills you.
