Toxic Deluge and Massacre both sweep their small mana-creature board (Elvish Mystic, Llanowar Elves, Fyndhorn Elves, and Badgermole Cub) before they reach a critical mass for Craterhoof Behemoth or Natural Order. Orcish Bowmasters comes in alongside them: its enter trigger deals 1 damage to a 1/1 mana creature and amasses Orcs 1, and it can flash in at the end of their turn. Daze is weak since Elves isn't pressuring your mana early and the tempo loss of bouncing a land matters more than the counter upside. Keep Thoughtseize and Wasteland in to strip their key combo pieces and punish their Gaea's Cradle-dependent manabase.
