Harxian Swamper

•When this card enters the battlefield, you may
destroy any number of swamp cards, and add
+2/+2 for every swamp destroyed in this way.
•If this card is currently in your discard pile, you
may destroy two swamps to put this creature on
the battlefield.
Some creatures rely on the swamp, some creatures use
the swamp. These things ARE the swamp.
