I'd want ~4" scale, so we can get planeswalkers as reg figs, and some cool ass summons as bigger figs, such as the titan cycle as 12" figs, or eventually eldrazi as 2-3' tall figs. Yes, the scaling wouldn't be perfect, but admit it, you'd be down for Galactus type characters like how the old 4" marvel line did.
Imagine a big noxol bolas fig hovering over a tezzeret with his latest orders, or tezzeret showing off his aethergate or w/e to bolas. You could buy multiple jaces to emulate his illusion magic, or Liliana has a few zombie army builders to create her swarm! Glissa with a short little slobad, and a tall Bosh to complete the trio! They come with sword, shield, and helmet of kaldra too!
Akroma, kamahl, phage, and a mirrari!
Liliana's pact demons! Karen, urza, and the new phyrexian praetors are cool too! Eldrazi spawn and myr as little bundles of very basic but multitudes of figs! Slivers!
There'd be huge potential, even if hasbro itself made them, but most of it is in old stuff, so I doubt they'd tap it properly... Heh, see what I did there?
