This deck is a twist on the classic Ravnica Allegiance gate deck with a new card, Song of Creation vying to put it over the edge to be a borderline competitive deck. If you want to see a more in depth look at the deck you can watch a short video deck tech here: https://youtu.be/eC59A8WEvdU
Thanks for checking this out!
NOTE: If you have access to a Uro, Titan of Nature's Wrath you can play it for one Archway Angel.
