Thoughtseize strips their Force of Will or Daze ahead of committing our key threats, since their deck otherwise punishes tapping out with countermagic and burn like Lightning Bolt. Once Upon a Time is a weak swap-in against a deck racing us with Dragon's Rage Channeler and Murktide Regent, since it doesn't affect the board or protect our threats. We shave one Wirewood Symbiote since its untap utility is a lower priority than proactive disruption against their fast clock. Keep our full mana creature suite intact to still enable turn-two Natural Order or Green Sun's Zenith into a game-ending threat.
