Fire Magic at its Fire mode kills an undeveloped Dragon's Rage Channeler (1/1 base) for free, and its Fira mode for {2} can clear the Monk tokens that Cori-Steel Cutter makes. A delirious Dragon's Rage Channeler is a 3/3 and survives Fira, so it needs Swords to Plowshares or the {5} Firaga mode. Fire Magic only damages creatures, so it can't answer the Cutter itself. That still makes it a cheap, efficient answer to their early creature threats. Consign to Memory counters colorless spells like Mishra's Bauble and also hits triggered abilities such as Cori-Steel Cutter's flurry trigger and Dragon's Rage Channeler's surveil triggers. It can't counter their blue cantrips or Daze, which are blue spells, so it is a narrow, situational include here. Prismatic Ending can answer Cori-Steel Cutter itself, but at sorcery speed it is slower than we want in this matchup. Swords to Plowshares already handles their creatures, and Fire Magic sweeps the Monk tokens. Flow State is too slow against this fast tempo-aggro deck. Keep Wasteland in to continue denying Volcanic Island and disrupting their explosive starts.
