Mono Red Rally wants to flood the board with cheap creatures before swinging wide with the hasty Human Soldier tokens from Rally at the Hornburg or a kicked Goblin Bushwhacker. Holy Light is strong here because -1/-1 wipes out Voldaren Epicure, Clockwork Percussionist, Goblin Bushwhacker, and Gingerbrute in one sweep. It won't kill Burning-Tree Emissary, which survives as a 1/1, and it doesn't affect the white Human Soldier tokens from Rally at the Hornburg. Revoke Existence answers Inventor's Axe or a troublesome Blood token, and can hit Great Furnace, an artifact land, if they overextend into it. Cut the slower, situational Novice Inspector and Search Party Captain along with Thraben Charm, whose damage output scales with your own low creature count early and is often too slow against this deck's turn-three kills. Keep the low curve and Ornithopter/Phyrexian Walker blockers intact since racing and trading on the ground is still central to beating their alpha strike.
