Shadow of the Fallen

Flying
Phase 2: Sacrifice a creature
(When this creature becomes target of a spell or an
ability an opponent controls or if you pay its phase
costs, exile it with 2 phase counters on it. Remove a
phase counter at the beginning of each turn. When
there are no counters left, put it back onto the battlefield.)
When Shadow of the Falling Angel enters or leaves
the battlefield, you may pay 2 life. If you do, draw a
card.
