Wormfang Newt

The Wormfang creatures all run the same mortgage-and-reclaim engine: enter by exiling a land you control, then hand it back the moment they leave the battlefield. This is the land-flavored member, and the one whose drawback reads gentlest while cutting in two directions. The exile costs you a turn of mana up front, but the return clause is where the play lives: the exiled land comes back when the body dies, and it returns untapped, ready to use immediately. That untapped return is the quiet detail separating it from a pure tax. Most "exile your own permanent" enter triggers leave you down a turn while the land creeps back tapped or replayed by hand; this one restores it in playable condition the instant the salamander is gone. The consequence is that any way to remove the creature on your own terms (blink it, bounce it, sacrifice it) effectively refreshes a land, and exiling a fetchland or another nonbasic you would happily re-enter inverts the downside into something closer to an asset. The trap lives in the trigger order, not in tempo. The leave-the-battlefield clause and the enter clause are separate triggers, so killing the Newt before its enter trigger resolves does not save your land: the leave trigger resolves with nothing exiled to return, then the enter trigger resolves and exiles a land permanently, with no salamander left to give it back. The design comes out of a period when creatures were bonded to a resource you already controlled, lending and reclaiming rather than generating from nothing, with the cost paid in tempo rather than cards.
