Saint Elenda [Alchemy: Outlaws of Thunder Junction]

Lifelink
When Saint Elenda enters, conjure a card of your choice from Saint Elenda's spellbook into your hand. You may cast that card this turn without paying its mana cost.
At the beginning of your end step, if you gained life this turn, create an X/X white Avatar creature token, where X is the amount of life you gained this turn.
