I really think that there should only be one angel token prayer between this one and the mythic. Currently, I am leaving toward the mythic, even with the slight flavor fail at the moment. (To whom are angels praying?)

I think the flavor fail is part of the reason the mythic loses that contest. The Mythic should be the exultation of the Faith, what the masses are praying for. I think the Mythic should be some Akroma/Archangel of Thune type card. Something that rewards the faithful.

The other aspect that's difficult to balance is that the pray cost is always the same across all the cards. So whichever card ends up with the "Make an angel" text will cost the same to activate as the other potential cards with that ability. I think it's more prudent to make that the focus of the card than an addendum to a 5 mana 4/4 flier with first strike.

Changed creature type to Cleric over Monk.

This is just the cleaner design, the mythic is stronger but I'd hardly say its more exciting. I vote for this design over the mythic.

@Doombringer: Does that mean you want this in the mythic slot rather than The Holy Harbinger?

If so, I could see that - if it becomes an Angel, too.

Note, Holy Harbinger has been changed to a different design.
