This card can also be obtained from Card Packs. Diamond Chests and Card Packs can give Premium versions of this card.
Alternatively, it can be used to remove a troublesome blocker, and then attack with it as well.
If you transform a unit you steal with a card like Unstable Form, you do not keep the transformed unit, and it will return to your opponent at the end of turn.
Cards you steal that die while under your control will go to your Void.
If you have a full board when you take control of a unit, the unit will go directly to your void.
