Meltdown cleanly answers Mishra's Bauble and Cori-Steel Cutter, both key value/payoff pieces for their prowess plan. Blood Moon turns off Spirebluff Canal, Steam Vents, Fiery Islet, and other duals, severely hampering their ability to cast Expressive Iteration and double-color spells while our deck is mostly castable off Mountains. Burning Inquiry is bad here since it hands them free cards into an aggressive low-curve deck that loves card advantage triggers like Dragon's Rage Channeler surveil and Cori-Steel Cutter tokens. We're cutting some redundant cycling since the matchup is more about surviving their clock than digging.
