Rescue

Bouncing your own permanent at instant speed is a deceptively deep template, and the bare-bones version of it lives here: no extra clause, no cantrip, no upside beyond the act itself. The value sits entirely in the target. Save a creature from a removal spell on the stack. Pick up a permanent before a sweeper resolves. Reset a permanent so its arrival ability fires a second time. Reuse a tapped-out utility creature after its ability has already paid out. The single blue mana is the whole pitch: the spell wants to be held up alongside something else and spent reactively, which is why it reads as a tempo-neutral safety valve rather than a card you cast on your own initiative. Later designs narrowed the effect to make it pay for itself (cantrips, untap riders, mana refunds), but the unadorned version trades raw card economy for the lowest possible cost of holding the option open. That is the tension worth naming: bouncing your own permanent is almost always a one-for-one card disadvantage, so the only justification is the moment, and the spell is priced so the moment never costs more than a single untapped land. It is interaction defined by timing rather than by what is printed underneath.
