Egon, God of Death // Throne of Death

A 6/6 with deathtouch for three mana would be flatly undercosted if the front face did not come with a fuse burning from the moment it lands. Every upkeep it demands two cards exiled from your graveyard, and the instant the bin runs dry the God eats itself and hands you a single card as consolation. That self-destruct clause is the entire balancing act: it converts an oversized stat line into a resource you have to keep feeding, and it means the card is only comfortable wedged into a shell already committed to self-mill. The two faces are two ends of the same tension. The front drains the graveyard; the back, Throne of Death, restocks it a card at a time and pays black-and-two to turn creature cards in the yard back into fresh draws. Because you pick one end at cast rather than flipping between them, the choice is which problem you would rather have: the fragile monster that closes games when it survives, or the slow engine that feeds the monster's upkeep once both are on the board. Neither half stands alone. One exiles from the yard, the other refills it, and the whole thing coheres only if you engineer the fuel around them both. Egon rewards the deck already built to fill its own graveyard and punishes the one that expected a cheap beater to fend for itself.
