Dystopia forces them to sacrifice a green or white permanent every upkeep, which eats their enchantments (including engine pieces) and Solitary Confinement before it locks you out. Ravenous Rats and Withered Wretch do little against a deck with no reliance on its graveyard and few creatures to strip hand-wise, so they make way. The extra Diabolic Edict helps handle Argothian Enchantress, their only real creature-based engine piece. Keep Duress and Cabal Therapy in to strip Replenish-style payoffs or key enchantments before they resolve.
