Mantle King Doursummons

When this creature enters or leaves the battlefield, it deals damage equal to twice its power to any target.

If this creature would die and it isn't a token, you
may create a token that's a copy of it, except it has base power and toughness 1/1. If you do, shuffle this creature back into it's owner's library.
