Doomsday wins by assembling a five-card stack culminating in Thassa's Oracle, and revealing Chancellor of the Annex from our opening hand counters their first spell of the game unless they pay {1}, disrupting their opening turn. We cut Call Forth the Tempest since it's the clunkiest cascade spell to cast and doesn't interact with their combo at all. The real gameplan here is applying fast pressure with our cascade threats since Doomsday decks are often tuned to combo off rather than block, so prioritize proactive plays over durdling. Note that Leyline of the Void does not stop Street Wraith cycling or their combo, so we leave it out and prioritize Chancellor of the Annex to slow them down.
