* Dragsolution: When the equipped creature would leave the battle zone due to one of your opponent's spells or creature effects, flip this dragheart to the creature side and untap it instead.
(At the start of your game, draghearts are put into your hyperspatial zone. If a creature equipped with it or the dragheart leaves the battle zone, return it there.)
