UB is a closely related cantrip-tempo deck leaning on Stormchaser's Talent and Thoughtseize rather than Wasteland or countermagic-heavy disruption, so punishing their card selection is a priority. Orcish Bowmasters taxes every Brainstorm, Ponder, and Mishra's Bauble they crack, while Fatal Push answers their Murktide Regent equivalent threats or an early Stormchaser's Talent creature cheaply. Daze trades symmetrically against their own copies and isn't worth the tempo loss in a grindy mirror-like matchup, and Lotus Petal is less needed when neither side is racing hard. Grind out card advantage with Bowmasters and Thoughtseize while protecting your best threat with Force of Will.
