A ridiculous card draw engine with Dreadship Reef, Vivid Creek, and the rest of those cycles in modern. Kinda like Confidant but without the life loss, two extra toughness, and a different deckbuilding restriction.
Keep in mind that this is for the control deck, and you'll want to be holding onto cards for as long as possible. This could easily make a 4/4 or larger in many cases.
This is like the timmy-est card ever, I love it. All you have to do is crew it once, and it just snowballs out of control into a ridiculous angel factory.
Wait, if they wanted a mono blue, human female transmuter to add to the roster of 'walkers, why not just have it be Jalira? She could have easily ignited off-camera.
This has the potential to be so broken in a Modern Superfriends deck with fetches. Also, you can potentially use Kiora, the Crashing Wave's minus every turn and actually BUILD loyalty over time.
If you tutored for Mowu, Loyal Companion with this, would he enter with one counter or two? Either way, this card seems super good as a cheaper but more restrictive Eldritch Evolution.
Side note, since Hazoret is still kicking, this was a clever way of making a full five card cycle of monocolored gods in the set.
