Impetuous Devils
Six damage of trample-and-haste that you point at a single blocker the defender cannot refuse: the attack-trigger forces one chosen creature to step in front of it, turning the 6/1 body into a guided removal missile that dies on the same turn. The lethal one toughness is the whole bargain. This thing is built to be thrown, not kept, and the forced-block clause is what converts its glassy frame into reliable creature destruction rather than a fragile swing that the opponent simply waves through. Trample matters precisely because the chump it conscripts will rarely have six toughness, so the excess bleeds onto the player. Read in sequence, the three lines tell a complete story: arrive immediately, drag down whatever you choose, then vanish before it can be exploited as a permanent. The end-step sacrifice is not a downside bolted on; it is the cost that pays for the rate, ensuring you rent the effect for a turn instead of owning a six-power evasive threat for four mana. The forcing target is also strictly optional ("up to one"), so against an empty board it simply connects for six. What makes it a devil in design as well as type is the Faustian shape of the deal: maximal violence on entry, guaranteed self-immolation on exit, and a single combat window in which to extract value before the contract comes due.
