Procrastinate (SOS)

Sorcery

Tap target creature. Put twice X stun counters on it. (If a permanent with a stun counter would become untapped, remove one from it instead.)

Niche tempo tool for control and tempo decks, but stun counters require setup and commitment of mana that's often better spent on permanent answers or card advantage. The scaling potential with X is real in longer games, but the effect remains temporary and vulnerable to creature removal or bounce.
