Hydroblast is excellent here, countering or destroying Fiery Temper, Lightning Bolt, and any other red spell, while Pyroblast and Red Elemental Blast stay home since the opponent casts no blue spells (Sneaky Snacker just returns itself from the graveyard on a third draw). The second copy of Breath Weapon deals 2 damage to each non-Dragon creature, wiping Voldaren Epicure, Sneaky Snacker, and Guttersnipe, though not the 1/3 Kessig Flamebreather, which is huge against their token-and-engine board. Lose Focus and Crop Rotation are too slow and situational against a fast burn plan, so they come out. Keep leaning on Moment's Peace and Stonehorn Dignitary to buy time, and Mulldrifter/Pulse of Murasa to stabilize the race.
