Pyroblast is live against Counterspell, Spell Pierce, Brainstorm, Preordain, Lorien Revealed, and Baleful Strix, giving us cheap, efficient answers to their permission and card selection in this control mirror. Envelop adds a free counter for their sorceries like Preordain or Lorien Revealed. Moment's Peace and Weather the Storm matter less against a grindy control deck without an aggressive clock, so they make room for more targeted disruption. Lean on Mystical Teachings and the artifact mana package to out-value their incremental card advantage from Baleful Strix and Murmuring Mystic.
