Tirany Primal Enchantress

Changeling (This card is every creature type.)
Whenever you cast an enchantment spell, with a
mana value of 3 or less, you gain life. Otherwise
you may draw a card.
At the beginning of your end step, if you control
three or more enchantments, then return her to
the battlefield transformed under her owner's
control.
"Wonderful, again!"
