Mark of Mutiny - Iconic Masters (Common) [IMA-139]

Mark of Mutiny allows you to take control of an opponent's creature for a turn, boosting its power with a +1/+1 counter and granting it haste. This can create surprise attacks or block a key threat, making it useful in aggressive red strategies that aim to overwhelm opponents quickly. However, its temporary control means you need to use it effectively during that turn to maximise its impact.
