Expel {12}, flying, haste, trample, lifelink, indestructible, anihilator 3
If a nonchaotic, nontoken creature would die,
exile it with a knot counter on it instead. Then,
you may roll the Chaos Library.
You may cast exiled cards with knot counters on
them by paying life equal to their converted
mana cost instead of their original mana cost.
