Field spells used to be cards that gave your monsters a slight boost, while transforming the battlefield into some sort of mountain or forest (well, at least it did in the anime!) Nowadays, Field spells add a whole new level of consistency to your deck, allowing you to search additional monsters, special summon for free, or lock your opponent out of certain effects
This will, of course, have you building a deck with all the best Angels, Demons, and Dragons you can get your hands on cards like: Master of Cruelties Avacyn, Angel of Hope Terror of the Peaks 1 Giada, Font Of Hope Ramp And Power Easily the most consistent and powerful Angel commander you can run is the savior of New Capenna, Giada, Font of Hope
This ability was represented on Future shifted cards peeking at possible future features
With how stunning this illustration is, it is no wonder as to why countless collectors want to get their hands on this card as soon as possible
Given it's once per turn I don't think it's going to slot that well into "not your hand" decks
