Bloodscale Prowler

Bloodthirst was the keyword built to reward decks that hit first and ask questions later, and this is the cleanest expression of the deal: a 3/1 that grows to a 4/2 the moment any opponent has taken damage that turn. The body tells you exactly who it was for. Three power on a one-toughness frame already wants to attack rather than block, and bloodthirst pushes harder in the same direction, turning the card into a downstream payoff for an aggressive curve that has already started chipping away. The tension is that the upside is conditional on tempo you have to generate elsewhere: a burn spell to the face, an earlier attacker connecting, a one-drop getting in. Resolve it on an empty board and you have a fragile 3/1 that any X/1 trades with and most removal laughs at. Land it after the damage has been dealt and you get a 4/2 for three, a rate that closes games a turn faster. That is the bloodthirst bargain in miniature: the keyword does not generate the aggression, it asks you to have already committed to it, and rewards the decks that sequenced their turns to deal damage before this hit the board rather than after.
