Magebane Lizard punishes their cantrip-heavy plan, pinging them every time they chain Opt, Sleight of Hand, or Prismari Charm, and its 4 toughness survives an unkicked Burst Lightning, though a kicked one deals 4 and will kill it. Soul-Guide Lantern slows Eddymurk Crab's cost reduction and Hearth Elemental's graveyard discount while giving you a cantrip of your own. Plasma Bolt is the weakest removal here since it rarely kills their Hearth Elemental or Eddymurk Crab outright, so it's the easiest cut, alongside trimming Tomik and one Burst Lightning since this matchup is more about racing through interaction than maximizing damage triggers. Keep your clock as fast as possible since they need several turns to assemble their value engine.
