Oops! All Spells is a zero-land combo deck that wins by milling its entire library with Balustrade Spy or Undercity Informer, then winning through Thassa's Oracle or Dread Return. Blood Moon is completely dead here — the opponent runs no basic lands and generates mana almost entirely through Elvish Spirit Guide, Simian Spirit Guide, Dark Ritual, and Lotus Petal rather than lands. Null Rod is your strongest disruption, cutting off Lotus Petal and forcing the opponent to rely solely on creature-based and ritual-based acceleration. Disruptor Flute naming Creature taxes Balustrade Spy and Undercity Informer by two mana each, potentially buying a crucial extra turn. This matchup is fundamentally a race — Magus of the Moon and your threats don't stop their combo, so prioritize Null Rod on turn one and use Karn to find Null Rod or Mycosynth Lattice if you need to go long.
