Covenant of the Chosen

When Covenant of the Chosen enters the battlefield, choose a creature type. Creatures you control of the chosen type get +1/+1 and have protection from black and red.
At the beginning of your upkeep, if you control a creature of the chosen type, you may create a 1/1
white Spirit creature token with flying.
Whenever a creature of the chosen type dies, you
may draw a card.
