I played an End-Blaze Epiphany while having a Spinerock Tyrant on the board. The End-Blaze Epiphany was copied so I could deal damage to two creatures. Both creatures were destroyed, but no cards were exiled . It should exiled as many cards as the creatues power in 2 piles and let me chose 1 card from each play and play until the end of my next turn.
