Fast Asleep

If Fast Asleep is in your opening hand, you may
begin the game with it on the battlefield.
Whenever you cast a green spell, you may gain 2
life and put an awakening counter on Fast Asleep.
Then, if there are at least 3 awakening counters on
Fast Asleep, you may sacrifice it. If you do, create
a 0/7 green Plant creature token with hexproof.
