This is a creature mirror-style race between two aggressive green decks, so Tormod's Crypt is useful mainly to strip Squee, Goblin Nabob from their graveyard and shut off any Survival of the Fittest recursion loops, denying them a discard target to rebuy. Patrol Hound is the easiest cut since its first strike ability matters little against their bigger goblin bodies and burn. Keep your full removal suite of Swords to Plowshares and your low curve of Rootwalla, Wild Mongrel, and Arrogant Wurm, since matching their speed and using Rancor to push through extra damage is your best path to winning the race. Glory is also valuable here as a way to survive a key combat or Lightning Bolt-style burn spell from their sideboard.
