Battle-Rage Blessing

Two keywords bolted to one creature for the duration of a turn, and the pair conspires into something closer to removal than to a pump spell. Deathtouch means the target only needs to connect once, so any body becomes a lethal blocker or a lethal attacker regardless of its size. Indestructible then guarantees the creature survives the exchange it just won: the trade never runs both ways. Handed to a blocker, it devours the attacker and takes nothing home; handed to an attacker, it forces the opponent to eat the hit or throw a creature into a fight already decided. The real work happens in the interaction, since indestructible also shrugs off a destroy-based kill spell aimed at the creature once it has resolved, or the fixed damage of a burn effect meant to trade with the creature. So a card that reads like combat aggression functions as protection and ambush at once, resolving the instant blocks are declared and rewriting the arithmetic of a single combat. As an instant, its edge is entirely in the surprise: it does its one job and heads to the graveyard, so the opponent who walked into the block gets no rematch.
