Deathtouch

The Litch enters the battlefield with two doom counters on it.

At the beginning of your upkeep, remove a doom counter from The Litch. Then, if there are no doom counters on The Lich, destroy all other creatures and put three doom counters on The Litch.

If The Lich would die while it is your champion, exile it instead. You may cast The Lich as long as it remains exiled. When you do, it becomes your champion.
