Definitely a WIP. But... Pelt -> Ramp Dorks & Tokens -> Mass Poly or Shimmerpack a few turns early for an OTK is the idea. If you don't have OTK board presence and a bunch of hot garbage in hand, Hatcher + Pelt can turn that hot garbage into 5/5 hot garbage with flying.
Still iffy on no obelisks, but the idea is that pelt fits the pump role at a discount. It doesn't require maintaining 8 power, aka you can Shimmerpack your ramp dorks without the classic drawback of it bringing your obelisks down to +1/+1.
Premium playset of Unstable Form is 100% necessary to play the deck, the rest can be tuned to your liking.
