Flight of the First Phoenix

When Flight of the First Phoenix enters the battlefield and at the beginning of your draw
phase, create a 0/1 red Phoenix Egg creature
token with "At the beginning of your upkeep, sacrifice Phoenix egg and create a 3/2 red
Phoenix creature token with flying".
Whenever a Phoenix you control dies, exile the
top card of your library. Until the end of your
next turn, you may play that card.
