Mono Red Rally floods the board with small bodies like Burning-Tree Emissary (2/2), Voldaren Epicure (1/1), and Clockwork Percussionist (1/1) before Rally at the Hornburg or Goblin Bushwhacker pumps for lethal, so Holy Light's -1/-1 to nonwhite creatures wipes most of their early board in one instant. Thraben Charm's damage mode, scaling with our creature count, can also pick off key pieces like Goblin Tomb Raider or Burning-Tree Emissary before they go wide. We cut Phyrexian Walker and two Martyr's Soul since they're too slow and don't block profitably against a deck this explosive; this matchup rewards answers over bodies. Holding up interaction to disrupt their critical mass is more important than racing, since they can go lethal as early as turn three.
