This is a grindy value mirror full of Ephemerate/Flickerwisp blink loops and card advantage engines like Orcish Bowmasters and Overlord of the Balemurk, so High Noon is huge, slowing down their ability to chain Thoughtseize into blink shenanigans in the same turn. Celestial Purge answers their black threats like Emperor of Bones or Overlord of the Balemurk outright with exile, dodging any blink or recursion. Bribery is a strong finisher that steals their best creature, likely Atraxa, Grand Unifier or Griselbrand-adjacent threats if applicable, though here it grabs Atraxa or Quantum Riddler. Spell Snare is weak since few of their key cards cost exactly 2, and Isochron Scepter is too slow against their disruption-heavy hand attacks.
