迷醉渊的莎蕾 (Sharae of Numbing Depths) (zhs)

Legendary Creature - Merfolk Wizard | Power/Toughness: 2 / 3 (CMC 4)
When Sharae of Numbing Depths enters the battlefield, tap target creature an opponent controls and put a stun counter on it. (If a permanent with a stun counter would become untapped, remove one from it instead.)
Whenever you tap one or more untapped creatures your opponents control, draw a card. This ability triggers only once each turn.
