Creature â Human Shaman
At the beginning of your upkeep, create a 2/2 green Wolf creature token.
: Tap all untapped Wolf creatures you control. Each Wolf tapped this way deals damage equal to its power to target creature. That creature deals damage equal to its power divided as its controller chooses among any number of those Wolves.
The controller of the target creature doesnâ€™t divide that creatureâ€™s damage as the ability is activated (since the Wolves that will receive that damage arenâ€™t targeted), so that player does so as the ability resolves. There is no time to react between the time a Wolf is chosen, the time damage is dealt to it, and the time itâ€™s destroyed for having been dealt lethal damage. If you want to put a regeneration shield on one of those Wolves, or target it with a damage-prevention spell, or anything else, you must do so before the ability resolves (and before you know which Wolves will be chosen and how much damage will be dealt to them).
Only a Wolf creature tapped as part of the abilityâ€™s effect can be dealt damage by the target creature.
If the target creature is an illegal target by the time Master of the Wild Huntâ€™s ability tries to resolve, the ability doesnâ€™t resolve. You wonâ€™t tap your Wolves, and nothing will deal or be dealt damage.
All Wolves you control are tapped as part of the activated abilityâ€™s effect, not as a cost. Players may respond by attempting to tap or untap Wolves, or to create or remove them.
