Swords to Plowshares cleanly exiles Exalted Angel before its lifegain trigger spirals out of control, and also answers a morphed threat before it flips. The extra Cabal Therapy helps strip Vindicate, Gerrard's Verdict, or Wrath of God from their hand before it can disrupt our plan. Stifle again has minimal targets against BW Control's largely non-activated-ability permanents, so copies come out; Vision Charm is also low-impact here since they have no Dreadnought-style combo piece or key activated ability worth countering.
