Currently debating on whether I want this deck more, or if I want to shell out for FTV:20.

I'd shell it out for FTV. Jace's price will only rise, while this is a deck whose core is rotating in a year.

Eh, thing is I don't really play any non-standard format irl. I have an EDH deck but that's used only very rarely. I'm honestly fine with a core that will only last a year, since when RTR block rotates I'll have uni to focus on. Jace's price is negligible in this since I'd never sell it or trade it off.
