Izzet Delver's Mishra's Bauble is colorless, so Consign to Memory is a cheap, efficient answer, and Null Rod shuts off Cori-Steel Cutter's equip ability along with any other artifact activated abilities they rely on. Cabal Therapy is weak since the deck doesn't hinge on one namable card, and Wail of the Forgotten is too slow against their fast clock. We keep Daze and Force of Will at full count to fight through their own free countermagic while protecting our threats. Orcish Bowmasters stays strong against Dragon's Rage Channeler, since its damage can kill the Channeler before it reaches delirium. Neither Orcish Bowmasters nor Moonshadow can block Murktide Regent or a Channeler that has gained flying, so we rely on countermagic to handle those threats.
