Death or Glory

The pile-split mechanic is what makes this more than a graveyard reanimation spell: you do the dividing, but your opponent picks which half survives, which means the spell punishes its own ambition. Stack every fattie into one pile and the opponent simply exiles it; the only piles that come back are the ones balanced carefully enough that your opponent cannot find a clean side to deny you. This is a self-limiting payoff, a mass return where the size of the swing is negotiated against an adversary's veto rather than handed over wholesale. It belongs to the family of "Fact or Fiction" splits that Invasion explored, where the divider sets the terms and the chooser claims the value, except here the stakes are bodies on the battlefield rather than cards in hand. The reward scales with how unwilling you are to give anything up, and that tension is the whole exercise: a wide, even graveyard of comparable threats rewards the spell, while a hoard built around one bomb defeats it. For five mana it can stage a board out of nothing, but only for the player who fills the yard with creatures the opponent would hate to hand back either way.
