My problem with any M:tG based D&D setting is that Spellcasting works FUNDAMENTALLY DIFFERENTLY between the systems. Any even semi-accurate model of MtG casting in D&D will break all the rest of the math in the game. Any functional D&D game shoehorns MtG casters including planeswalkers into D&D Pseudo-Vancian casting.
It's just not a good fit.
