MAINBOARD CHOICES
4 of Rakdos Cackler
This card is just sweet. A 2/2 for 1 CMC with a "drawback". The reason I didn't go for Stromkirk Noble is because at 1 CMC, it just isn't quite doing what we want it to be. For me, he's just always under performed.
4 of Ash Zealot
A bear that has haste, first strike, and a relevant graveyard hate ability is always going to be great. Snapcaster Mage that Dissipate? Lightning Bolt to the face! End of turn Think Twice? Lightning Bolt to the face! Flashback Lingering Souls? Lightning Bolt to the face!
4 of Young Pyromancer
A reasonable body at 2 CMC with a powerful token ability. With 16 instants and sorceries in the mainboard and 7 more in the side, activating him isn't going to be too difficult.
4 of Chandra's Phoenix
All this is is a 3 CMC Ash Zealot with evasion. The ability is sometimes relevant, but that's not why we're playing it.
4 of Hellrider
A magnificent finisher. If we're on curve and go turn 1 Rakdos Cackler, turn 2 Ash Zealot swing for 4, turn 3 Chandra's Phoenix swing for 6, turn 4 Hellrider swing for 12, as well as the game.
4 of Madcap Skills
I want to know what R&D was thinking when they let this through. 2 CMC for 3 repeatable damage and evasion. If we play this on our Rakdos Cackler, we've just put our opponent on a 4 turn clock!
4 of Searing Spear
Unbiased removal that hits into most of the current standard meta that can also close out the game.
3 of Shock
Filler burn spell for when Searing Spear or Flames of the Firebrand just won't cut it.
1 of Lava Axe
A finisher for if the board has stabilized and we've gone into topdeck mode.
4 of Pillar of Flame
Great for removing blockers, and dealing with that pesky Voice of Resurgence.
4 of Flames of the Firebrand
I am just in love with this card. This consitently 2 for-one's against Lingering Souls, Arbor Elf, Elvish Mystic, Avacyn's Pilgrim, and things of that nature.
2 of Ghost Quarter
Deals with problem lands like Kessig Wolf Run, Nephalia Drownyard, and, if need be, we can use it on our own land to thin out our deck.
18 of Mountain
Red deck. Needs red sources. Pretty self explanatory.
SIDEBOARD CHOICES
2 of Burning Earth
Punishes the greedy mana bases of Jund, UWR, anything that runs three or more colours.
2 of Possibility Storm
Good against control and Jund. I'm serious. It hurts counterspells and kill spells.
3 of Volcanic Strength
For the aggro mirror matches.
4 of Skullcrack
Stops the ever common Thragtusks and Sphinx's Revelation from blowing us out.
4 of Traitorous Blood
Steals said Thragtusk, among other things.
