- 18 April 2017Time to Reflect only cares that the second creature was a Zombie at the moment it blocked or became blocked by the target creature. If that Zombie has become a non-Zombie creature or left the battlefield, Time to Reflect can still target the first creature.
- 18 April 2017Time to Reflect can target a creature that’s currently blocking or being blocked by a Zombie, or one that blocked or was blocked by a Zombie earlier in the turn.
