When Sharae enters, 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.

2 rulings from Wizards of the Coast
- 1 September 2023Sharae of Numbing Depths's last ability will trigger only when an effect instructs you to tap one or more creatures your opponents control. It won't trigger if a spell or ability you control instructs an opponent to tap a creature they control. For example, if you control Tangle Wire and an opponent taps an untapped creature they control as part of the resolution of Tangle Wire's triggered ability, Sharae's ability won't trigger.
- 1 September 2023You may target a creature that is already tapped with Sharae's first ability. If the target creature is already tapped as it resolves, you will still put a stun counter on it.
