Patron of the moon can be flashed in during a computation (if when we resolve the desolation giant we have a necromancer set up to make a moonfolk)
Looks like rotlungs don't work on their own; I believe the previous proof involving them was in a setting where they could be given indestructible or have damage prevented to them, and only proved that the base toughness of each creature type can be made consistent
The first deck doesn't work because the tokens from Rapacious One can be sacrificed in a computation.
The second deck has Brudiclad which can turn damaged creatures into goblin boom keg.
Can we just arrange for some DN triggers to be on the stack after a computation? Creating a starfield of nyx and a march is sufficient for the next spitting image to copy whatever we need from the opponent.
Though, March is a bit awkward to bounce at instant speed since it makes Soul Separator not work.
(edit: or we just directly get triggers for orrery and omni which is probably easier)
Ah; it does work, as we can order the cast triggers to put a TYS[Spitting Image] trigger after each Volute[Retract] trigger (with Volute[PFE] triggers in between as needed too).
Looks good, though I think we need flying and lifelink on the same creature. (Alternatively, replace Scarecrow for another artifact creature + another damage preventer, e.g. Runed Halo).
There is mirrormade in the deck, so that can be used to make omni tokens.
Then when the opponent has an omni, we can play mirrormade and in response to its triggers bounce omni and DN - then we end up with omni tokens that don't belong to a DN while keeping the original omni in hand; allowing it to be used to put a trigger on the stack for hyperstage transitions.
Edit: There are a few things that bounce lands of certain basic land types only. Sink into takenuma works but we're down a blue creature. Fathom Seer works (I think - opponent can't unmorph it) but needs two islands.

However, how do we actually have nontoken copies of Urborg Syphon-Mage enter the battlefield efficiently in order to create hasted tokens?
Edit: In fact Sphinx of the second sun is too late to matter as it only works after the only combat step

(edit: Chandra, Torch of Defiance does this too but from the library which is harder to use)

Oh, Glowing Anemone can bounce Blackcleave Cliffs allowing it to be discarded to Nihilistic Glee and returned with Restore again. I think that allows us to avoid using Worldfire which is a problem.

Edit: (Glowing Anemone, Moraug, Curse of Bounty -> Sink into takenuma, Sphinx of the second sun, Awakening) doesn't look like it loses anything (then of course we use Indatha Triome or Savai Triome)
