A 1/7 that swings as a 7/1: the power-toughness switch turns a creature built to absorb damage into one that delivers it, but only on the turn it attacks. The split body is the whole bargain. Park it on defense and it walls almost any ground attacker behind that seven toughness; send it in and the swap inverts the stats just long enough to land seven damage, then it reverts to a 1/7 wall before the opponent's combat step. Reading the timing precisely is the trick. The switch lasts until end of turn, so the creature is a 7/1 through your entire turn, including the second main phase and your end step, then snaps back to 1/7 before your opponent untaps. That asymmetry is what the design is selling: a body that is genuinely hard to remove in combat at rest, yet hits like a five-drop fatty when it commits. The cost of that flexibility is fragility in the swung state, where any pinger, blocker, or one-damage effect kills it dead during the window it matters most. An attack-triggered stat switch reads as gimmicky on paper and plays as a real tension every time you weigh whether this turn is the turn to send it.
