I wrote about the most interesting cards in Magic Origins for Paste.
Like the Archangel of Tithes:
This is an angel who flies around and generally makes your life more difficult. That’s the general tone of angels in Magic, so you have to wonder about the theological biases in the design time, but this card is excellent because it just slows everything down. It makes the game more expensive for the other player, and it actively discourages them from being able to do anything against your roving band of angels or whatever you want it to be.
