Patron of the Sentire

Elemental offering (You may cast this card any time you could cast an instant by sacrificing a
Elemental and paying the difference in mana costs between this and the sacrificed Elemental. Mana cost includes color.)
When Patron of the Sentire enters the battlefield, creatures you control gain lifelink, trample and get +X/+X, where X is Patron of the Sentire's power until end of turn.
