Ludevic, Necrogenius // Olag, Ludevic's Hubris

The flip side is an open-ended reanimation engine dressed as a transform card: Olag arrives wearing a creature card pulled straight from your own graveyard, rebranded as a 4/4 blue and black Zombie and reinforced by one extra +1/+1 counter for every card you feed the activation, the copied one included. That transform cost charges the same power twice: four colored pips plus X generic, then that identical X paid again in creature cards exiled from the yard. Every point of X is at once a mana sink and a graveyard levy, since each exiled creature both enters the pool of possible copy targets and swells the finished body. That double duty is what promotes the front face's mill from filler to fuel; the Wizard spends its combats stocking the yard with bodies it fully intends to devour into whatever the best buried creature turns out to be. Because the transform is sorcery-speed only, Olag never ambushes anyone mid-combat: assembling it is a declared, telegraphed turn. The genuinely mutable element is Olag's identity, which resolves in two beats. The pool is locked in at activation, exiled up front as a cost; the specific creature copied is picked later, as the transform resolves. That split reframes deckbuilding as a question of which dead creatures you want waiting in reserve to be raised by imitation, and how deep into the ritual you are willing to commit to raise the biggest one.
