Rulings
You don't choose a target for Hurska's last ability at the time it triggers. Rather, a second "reflexive" ability triggers when you pay {G}{W} this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.

The value of X is calculated only once, as the reflexive triggered ability resolves.
