Consecrate // Consume

The two halves answer entirely different problems, and the split-card frame is what lets a single slot cover both. Consecrate is graveyard maintenance with a cantrip stapled on: cheap, instant-speed, castable off either white or black, the kind of answer that keeps a deck from drowning in an opponent's recursion while replacing itself. Consume is the payoff half, an edict tuned to bite harder than the standard version. An ordinary "sacrifice a creature" leaves the choice entirely to the opponent, who can chump their own effect by keeping a spare token around. This one narrows the pool to creatures with the greatest power, so a player sitting on one large threat and a pile of small bodies loses the big one; the life gain then scales with exactly what they were forced to shed. (The opponent still picks when several creatures tie at the top, so it is not a true snipe, just a floor on how much it costs them.) The tension is timing and mana, not any reuse clause: casting either half sends the whole card to the graveyard the way any split card does, so you never get both effects from one draw. The instant half wants to be held for a graveyard-dependent spell on the stack; the sorcery half wants four mana untapped and a fat creature across the table. What the pairing buys is not flexibility within a turn but optionality across a game: two narrow answers folded into one card, each waiting for the board state that makes it live.
