3 rulings from Wizards of the Coast
- 26 July 2024You don't choose a target for Wick's Patrol's ability at the time it triggers. Rather, a second "reflexive" ability triggers when you mill three cards this way. You choose a target for this ability as it goes on the stack. Each player may respond to this triggered ability as normal.
- 26 July 2024If your library has two or fewer cards in it when Wick's Patrol's ability resolves, you'll mill as many cards as you can, but the reflexive ability won't trigger.
- 26 July 2024The value of X is calculated only once, as the reflexive ability resolves.
