MAGIC: THE GATHERING
|Type:||Creature - Nightmare Dragon|
When Worldgorger Dragon enters the battlefield, exile all other permanents you control.
When Worldgorger Dragon leaves the battlefield, return the exiled cards to the battlefield under their owners' control.
Worldgorger Dragon is an interesting card that doesn't seem that strong at the surface. Why would I want to exile all of my permanents for a 7/7 Flyer with Trample? Well, when you use Animate Dead to reanimate a Worldgorger, you create an infinite loop of exiling permanents. Put in a Piranha Marsh or an Oona (and enough mana to activate) and you win!
