Zombie Infestation Aggro also runs Hermit Druid plus Shallow Grave/Reanimate to cheat Phyrexian Dreadnought or Sutured Ghoul into play quickly; Tormod's Crypt exiles their graveyard to deny reanimation targets after a Hermit Druid mill, and Diabolic Edict provides unconditional removal for a Dreadnought or Ghoul regardless of Stifle/Vision Charm protection. Circular Logic is weak against a deck that plays few countermagic-worthy spells and can easily pay the tax with cheap mana. Sickening Dreams is replaced since their creature count is low and situational. Keep Duress and Impulse to disrupt their combo pieces proactively and dig for your own interaction.
