Strange Inversion

Switching power and toughness is one of the oldest combat tricks in the game: a one-shot way to blow up an attack or turn a wide-bodied wall into a sudden threat, an effect that has surfaced across colors and eras as exactly that kind of situational instant. As a standalone spell, the rate is unremarkable for a single combat manipulation. The splice line is what gives it a second life. The mechanic works as a static modifier on a spell as you cast it: reveal this from your hand while casting another Arcane spell, pay the splice cost, and the swap rides along on a bounce, a burn effect, or whatever the host happens to do, all without committing the card itself to the stack. That structure is what makes the marginal effect repeatable without any recursion: the same physical card stays in your hand, revealed and paid for again each time you cast something it can attach to. It rewards a deck stitched together from Arcane spells, where every cast becomes another window to fold in the inversion, and it punishes any opponent who treats a high-power, low-toughness attacker as safe to block or race. Cast alone, it reads as a footnote. Spliced repeatedly onto a chain of Arcane spells, it becomes flexible combat sleight whose value scales with how many other cards in the deck speak its language.
