Jeskai Control has very few early creatures (Gran-Gran is the main one) so our removal suite is overkill; Fiery Impulse comes out since there's little to kill. Mystical Dispute is cheap against their many blue spells (Divide by Zero, Pop Quiz, Accumulate Wisdom, It'll Quench Ya!) and otherwise still counters anything for {3}. Disdainful Stroke stops Jeskai Revelation and Thor, God of Thunder, their two biggest swing spells. Into the Flood Maw has almost nothing worth bouncing since Gran-Gran is their only early creature, so we trim it for more counterspells to fight through their own counters and card draw.
