This is an interesting card for an Angel deck, but it's exceptionally weak elsewhere, and I personally wouldn't play it in Angel either. It has a massive inherent cost of 4, massive set up cost of having 3 Aerial characters in play, and underwhelming effect when it's all put together. Readying allies is a weak ability, so you'd love to ready other identities with it. But if your turn is before somebody, they might not be exhausted yet, and if your turn is after somebody, they won't have a use for being ready. This was intended to be played in an Angel deck due to Archangel dealing 4 damage after you play it, and Angel has lots of ways to help reach the resource cost, but it's so much less efficient than Angel's own cards and Air Supremacy even when you get it set up. I think it can be a fun casual deck, and this one by dr00 is highly upvoted if you want to give it a try:
