I think I've found a better ending sequence. But, it doesn't work with cheap card draw, so it's incompatible with the current Spitting Image plan. So, I've gone back to the Master of Ingenuity combo. Fortunately, it still fits.
I think that deck also needed darksteel citadel to keep coat of arms alive during computation (march is needed so our boom-keg dies). I dont remember the exact problem with the mirrormades there, but it seems very difficult to have them be all the enchantment we need them to be at the correct times. Bloodbond March and Spellweaver Volute for sure. Also, casting Army of the Damned doesn't seem to actually be able to convert into many computations as there's no workaround for retract.
Ooh, Urborg, Syphon-Mage looks interesting! Unfortunately, both Marchesa's Smuggler and Break Through the Line require expensive colors. Perhaps we could switch out red mana as the hyperstage resource for green? But, that could be difficult with Recoup apparently needed - in particular, it can give Worldfire flashback for cheap. Perhaps we can allow Worldfire to be cheap, but have Restore require the hyperstage transition?
What I would like to do would be to get rid of Thousand-Year Elixir, so that we could transition from Widespread Panic to Jester's Mask and then the usual ending layers, getting potentially 9 layers. So, I'm thinking about how we can switch our hyperstage resource from red to green. The only problem seems to be how we cast Distorting Wake or Stolen by the Fae. It looks like most cards that can allow other cards to be cast, either allow them to be cast immediately without paying their mana cost, or allow them to be cast while paying their mana cost some time in the future. I think what I would like would be a card that allows a sorcery to be cast immediately, while still allowing us to pay the mana cost. Are there any cards like that?
I guess we can have hasted creatures, if the only way to deal damage is the single combat phase that we have. But, I'm not sure what to transition Jester's Mask into in that case. I've typically been going to the opponent's library or combat at the end of the sequence; the former is below Jester's Mask, and we can't use the latter if we have hasted creatures.
So here we try to use green to get that 8th layer, but it's pretty inefficient, using 4 cards to get that one layer. (Arcane Sanctum + Animist's Awakening + Uproot, and also saving green to the end means replacing Molderhulk with Restore, which requires putting Panharmonicon back in) The rest of the layer sequence is pretty efficient, but with that green layer it barely fits. (hopefully)
The other deck uses the hasted creatures with just one combat idea:
Yeah, Precursor Golem gives another layer, so it's better than an additional Reality Spasm. And we do need Consecrated Sphinx to take up that blue creature slot. It seems easy enough to put artifacts into the library two at a time, so Consecrated Sphinx should be no trouble.
Hmm yeah, we don't have a good way to keep the nontoken Urborg Syphon-Mage on the battlefield. If we had Spitting Image, we could give the opponent a hasted token copy, and make copies for ourselves. That would be another reason to make Spitting Image work somehow - we would already like it for allowing us to keep Mirror Gallery. Still not quite sure how to make us able to cast Spitting Image at the cost of life though.
Otherwise, we can just switch Minion Reflector back to Dual Nature, and add a universal source of haste like Fervor. That costs us a Reality Spasm, which puts deck 2 in a tie with deck 1 again. Anyone have other ideas for how to give haste to Urborg more efficiently?
The problem is that we'd need to pay an additional R after every Worldfire, which I guess we can do via Graven Cairns? but I don't think we need to pay for haste for anything else and can just build up red that way so this looks like a dead end.
edit: we'd also need to somehow untap the hasted siphon-mage, which is not something we can afford to do cheaply. so this doubly doesn't work.
