Temporary Insanity

A steal spell that scales with your own recklessness. The four-mana price and the haste it grants put it in conversation with Threaten and the borrow-and-sacrifice line every red deck has run since, but the target restriction is what sets this one apart: the creature's power has to be strictly less than the number of cards in your graveyard. That clause inverts the usual cost structure. Early on the spell can grab only the smallest bodies, sometimes nothing, but in a deck built to fill the yard (a madness shell, a discard engine, the kind of self-mill the era rewarded) the threshold climbs fast, and by the midgame the condition stops mattering at all. It is a scaling effect dressed as a drawback, a conscription spell that gets stronger the longer it sits in your hand. The untap and haste do the standard work: pair it with a sacrifice outlet and the borrowed creature never goes home, and the untap lets you flip a tapped-out blocker the opponent thought was spent into a surprise attacker. The conditional target is also why it never became a staple, demanding a graveyard-shaped deck before it does anything while the decks willing to do that work usually had cheaper, more reliable payoffs. The interesting wrinkle is that the graveyard is only counted, never spent: the cards stay put, so the threshold ratchets up permanently as the game goes long rather than depleting with each cast.
