Crested Craghorn

A 4/1 with haste is normally a glass-cannon clock, but Provoke recasts it as something stranger: an attacker that drags an enemy blocker out of position the moment it lands. The two keywords work in concert. Haste removes the delay, so the creature swings the turn it resolves; Provoke then forces a chosen defender to untap and block, and four power kills almost anything in one exchange. The single toughness rarely costs you, because you pick the matchup: aim it at whatever you can profitably trade with and leave the bigger threats standing. The catch is the absence of trample. The provoked blocker absorbs all four power, so the kill and the combat damage are the same event, not two: this is not a clock plus a removal spell on the turn it provokes, it is a one-shot assassination tool that happens to walk around as a hasty body. Five mana for a 4/1 is steep, and Provoke only fires on a swing, so against an empty board you are left holding four power with nothing to drag forward. As a mechanic, Provoke has always been about converting an aggressive board into combat the defender never agreed to, and welding it to a high-power haste creature is the most literal reading of what the keyword wants: make them block, on your terms, this turn.
