Overall: Quad damage is hard enough to pull.
Unupped:
Ruby Dragon (12) + Momentum (13) + PU (26) + Sky Blitz (52) + Chimera + Draft (104). Dragon + Momentum can be replaced by any 2 cards that make a 13+ attack creature. 6 cards, bt's pretty unstable to get all that quanta, as any ol' OTK.

Pegasus (3) + Blessing x2 (9) --> Use Dive (18) + Sky Blitz (36) + PU (72) + Chimera + Draft (144) --> 8 cards, not viable for oetg meta. The 2nd blessing can be replaced for Momentum or Rage Potion, as it just needs 1 more attack.
Upped: 5 cards: Ruby Dragon (15) + PU (30) + Blitz (60) + Chimera + Draft (120).
The only thing that scares me about this combo is that it can be done with 2 Singularities. 3 if you add a Momentum, making it a 6-card combo powered by SN and only countered by a very early Black Hole & hand control. Or double dials, because the deck will surely pack a Deflag (this would make the combo need more than 12
but meh.
