Welcome to hyper aggro. The deck that either wins fast or loses hard.
This deck has a number of chances to win turn 1, but they all rely on getting at least one Simian Spirit Guide, and the fewer spirit guides, the more "free" spells you need, such as Mutagenic Growth or Gitaxian Probe. It's more likely to win on turn 2 or 3, and 4 is usually pretty slow and you are likely to be running out of steam or simply getting poor draws.
CREATURES
Monastery Swiftspear: Built in haste with prowess makes this the perfect one drop for this deck. This one makes the Tainted Strike infect win much easier to pull on turn 2, even as early as turn 1 if you're lucky.
Blistercoil Weird: The weaker, lesser version of Swiftspear, it can use your awkward singleton Island to get out and is nice for surprise blocking with its untap ability tacked onto the pseudo prowess ability. This is either supplemented or replaced partially with Nivmagus Elemental from the side.
Kiln Fiend: The creature that started me making this deck, his toughness never goes up by just the ability, but the much more potent power increase makes it worth playing this two drop. If Nivix Cyclops was somehow a 0/4 defender for one less mana, I'd prefer that even with the color intensity since Kiln Fiend has a dangerously boltable toughness, but that's the risk hyper aggro must take :P
Simian Spirit Guide: Barely a creature, but I suppose in a dire emergency that's how it could be played. It will 99% of the time be exiled for mana to make my greedy plays happen sooner.
SORCERIES AND INSTANTS
Lightning Bolt: Best removal in my main color, as well as being a cheap prowess/pseudo prowess enabler that can also quicken my win with an extra 3 damage per bolt. Great card.
Crimson Wisps: Card for fueling my greed, getting my wins to come a turn sooner in conjunction with Simian Spirit Guides, etc. It also is a cantrip if nothing else, so if nothing needs haste, it's still somewhat useful.
Manamorphose: Once I'm at two mana including or , essentially a free spell that color fixes and draws me a card. Commonly used to produce , but can help with getting Tainted Strike online if I can't get a black source. Also, prowess enabler.
Gitaxian Probe: Extreme value. Not only can I choose to pay 2 life instead exhausting mana to draw a card and enable prowess, I get to see what my opponent is holding in store for me. This is great for knowing when is the best time to try and go for the kill. Definitely good in game 1 for finding out what the opponent is playing in general.
Mutagenic Growth: Another "free spell" like Probe, but no card draw. Just strict boosting, as well as a form of protection. Any of my creatures will survive a bolt after getting hit with this. Also great for getting that quick win in.
Apostle's Blessing: The other form of protection in the deck right now, which also serves a role in giving evasion in case the opponent's field is cluttered. Recently added a Godless Shrine so it is possible to pay the full mana cost, but usually will be payed for with and 2 life. Important to note this also works against affinity as artifacts is an option besides just colors.
Assault Strobe: One of the main cards in getting the damage to become lethal quickly. One mana for double strike and enabling the abilities of my creatures gets things cooking fast.
Tainted Strike: The other compadre in finishing the opponent quickly. Giving infect means I don't have to try as hard to get the damage up. A Kiln Fiend only needs this and Assault Strobe and an open field to get the win. Great addition so far in testing.
Slip Through Space: New great spell from Oath. Makes it so my creature can't be blocked, triggers prowess, and now most importantly and why I finally included an unblockable granting spell, it cantrips, replacing itself so I don't run out of fuel as quickly. Great addition to the team.
LANDS
The land base has been a work in progress but should be fairly adequate now. It'll probably still get some work here and there, especially as I make more changes. I switched to cheaper fetch lands to lower the price (since Scalding Tarn is just too crazy), and have made sure to have the shock lands be as relevant as possible.
SIDEBOARD
Atarka's Command: This one would likely be main board if I wasn't concerned with trying to keep the curve as low as possible. This gets brought in for when I want to switch to a wider burn approach, and it just has great utility. It's nearly a more color intensive Skullcrack that I can tweak as needed depending on the situation.
Destructive Revelry: Enchantment and most especially artifact hate. I like this one for adding extra burn in when I need it switched in
Dismember: Switched in for facing decks that get fat creatures I can't bolt and indestructible creatures.
Grafdigger's Cage: For normal graveyard hate, decided to go with this to avoid relying on white mana being available for Rest in Peace.
Nivmagus Elemental: As I stated earlier, this guy will either supplement the other creatures in a game where I need more, or replace a couple Blistercoil Weirds when I need to maintain value against control.
Noxious Revival: More like OBNoxious Revival... Okay, I'm sorry. This is for decks with a nice slew of removal/discard, mainly for retrieving creatures. Another great use is for stringing cantrips together to get prowess triggers up higher, or getting back an Assault Strobe if I need two double strikers to finish the game.
Surgical Extraction: I really like this card, great way to disrupt graveyard plays, such as a Snapcaster Mage target, as well as just getting rid of good cards. If somehow a Tron land ended up in their graveyard, that'd really mess them up, but I can't really afford colorless lands in the form of Ghost Quarter in this deck. A multiplayer dream I suppose.
If you have any suggestions, please feel free to leave them in the comments below, especially for sideboard because I kind of just threw the current one together with cards I like :P
If you like the deck, please throw a +1 my way. Also don't be afraid to ask for me to look at your deck as well. You scratch my back I'll scratch yours ;)
