Rally combo wants to flood the board with Burning-Tree Emissary, Clockwork Percussionist, Voldaren Epicure, and token generators before Rally at the Hornburg pumps the team for lethal, and Breath Weapon's 2 damage to each non-Dragon creature sweeps virtually their entire pre-combo board in one shot. Cast into the Fire can deal 1 damage to each of up to two target creatures, finishing off any 1-toughness survivors like Clockwork Percussionist or Gingerbrute, or alternatively exile a key artifact like Inventor's Axe. Annoyed Altisaur and the Repurposer package are too slow and are the easiest cuts since you need cheap, immediate answers to their explosive starts. Prioritize casting Breath Weapon the turn after they commit their board, before Rally doubles down on the tokens.
