When The Wanderer Unleashes (Any player suffer 2 damage or Any Pylon heals 2 or the Wanderer heals 3), players can only choose to heal the Wanderer or a pylon if it can heal for the full amount.
Example: Pylons start the game with 9/10 health. Players may not choose to heal a pylon until they have dealt at least 1 damage, allowing the pylon to heal for 2.
