Blue Crest's Rage

When a Blue Crest Fatalis under your control
enters the battlefield put 10 burst counters on
Blue Crest Fatalis. Whenever Blue Crest Fatalis is targeted by a spell cast by an opponent, is blocked
or blocks, remove a burst counter. When all burst counters are removed destroy all other
permanents, this ignores Indestructible.
When Blue Crest Fatalis is put in the graveyard
or put into exile, you may put it in its owner's
library third from the top.
