Mystical Dispute is excellent since this opponent's deck is almost entirely blue and red spells, letting you counter their Opt, Consider, Sleight of Hand, or Prismari Charm for just {U}. Anger of the Gods cleanly answers Hearth Elemental, Sunderflock, and their Eddymurk Crab tokens, though note Eddymurk Crab is a 5/5 and survives. Spell Snare is cut because their 2-drops are mostly cantrips they're happy to lose, and Spell Pierce is trimmed since they'll often have {2} up given how cheap their curve is. Keep Spell Snare copies you still have on Stubborn Denial, which is their most important 1-mana interaction piece to blank.
