Sear's 4 damage is much better than Plasma Bolt against this deck, since it can answer bigger threats they stick while Plasma Bolt's low ceiling struggles against anything beyond their small creatures. Hexing Squelcher makes your threats resilient to their counterspell-heavy suite (Countersculpt, No More Lies, Spell Snare) and dodges their Get Lost and Erode less relevantly but still adds pressure. Tomik's prowess upside is low-impact here since this matchup comes down to raw damage output against their Day of Judgment and Pinnacle Starcage, so he's the easiest non-land cut. Try to play around their two copies of Day of Judgment by not overextending into one turn when possible.
