Big Daddy, Apex Predator

Flying, Menace
If damage would be dealt to Big Daddy, Apex Predator, it instead deals half as much damage,
rounded down.
At the beginning of each end step, remove a
change counter from Big Daddy, Apex Predator.
Then, if Big Daddy, Apex Predator has no change
counters, exile it and return it to the battlefield
transformed.
