Act of Treason (JMP-289) is a red sorcery from Jumpstart that temporarily seizes an opponent's creature. It gives you control of the target creature until end of turn, untaps it, and grants it haste so it can attack or tap immediately. As a short-term removal/steal effect, it is often used to steal blockers or finish off opponents by swinging with a larger creature for one turn.
