Swain, Grand General of Noxus

You may have creatures you control enter with a +1/+1 counter. If you do, you lose 1 life.

At the beginning of any combat phase, you may change the Power and Toughness of creatures you control.

If 2 or more creatures dealt combat damage to an opponent during your turn, you may sacrifice this creature, search your library for a card named "Swain, Demonic Overlord" and put it on the battlefield. Shuffle your library.
