Mulan, Crouching Dragon

Haste, hexproof
When Mulan enters the battlefield, create a 0/1 legendary dragon creature token named Mushu
with “{r}: +1/+0 until end of turn” and
“When this token leaves the battlefield, create
a copy of this token”, then put {x}
+1/+1 counters on that token.
The flower that blooms in adversity is the most rare
and beautiful of all.
