Grand Vindicator Tycarian

Flying Backlash (When this creature would take damage from a source you control prevent it and put that many +1/-1 counters on it.)

When Tycarian attacks, creatures your opponent controls get -X/-0 until end of turn, where X
is equal to the number of counters on Tycarian.
During your End Step any creature with
a power of 0 is exiled.
