Mark of Tzeentch

You can roll a dice each time a spell targets a friendly TZEENTCH SLAVES TO DARKNESS unit. On a 6, the spell has no effect on that unit.

6

9"

If successfully cast, pick 1 friendly TZEENTCH SLAVES TO DARKNESS unit visible to the caster. Remove that unit from the battlefield and set it up again wholly within range of the caster and more than 9" from all enemy units. That unit cannot move in the next movement phase.
