Climatic Final Battle

All creatures gain, Flying, Vigilance and +4/+2.
If after 5 turns the game has not ended, sacrifice
all creatures and exile this card.
This card will remain in play until 5 turns have
elapsed, even if its caster dies.
"During the final episode, all main characters
seem to become super powered and will use abilities
they've never had during the rest of the show."
