Trying to figure out a way to get one or two priest of urabrask in there since if you hit one and a spirit guide while going off you can start cycling your manamorphoses again. It is possible to fizzle before you find a second retriever if you tap out and start trying to go off immediately (which you should!). Although it means you'll just go off next turn with a hand full of cantrips and combo pieces instead and didn't cause a problem the one time it happened to me, it's obviously a weakness that would be nice to cover.
I honestly didn't even think of grim haruspex, fecundity and beck/call were just the first two that occurred to me. Well, aside from glimpse of nature The tokens from myr sire and hangarback are pretty key though yeah, I don't think the deck would function if you couldn't draw off them.
One thing that I learned quickly during goldfishing that might seem obvious to those who are a bit brighter, is to never cast summoning unless you're confident you can resolve beck or fecundity on the same or following turn. A lot of your cards are literal blanks if all you have is summoning. Also, multiple summonings in play mean you'll draw more cards from hangarbacks, so they're not totally dead after the first.
New list moves the alternate win con to main. Now can go off through mindbreak trap etc, and not just dead to angel's grace. Also realised that a priest of urabrask would obviously be better as a 4th spirit guide.
Edit: just noticed it doesn't work with hangarback.
