ToolmasterOfBrainerd Aretherk go nuts.
From the three playtesting games I did with this deck... it seems like it could really use some cmc = 3 card which is both a win-con and powerful in a non infinite scenario. Preferably it would be a creature so I can hit it with CoCo. Not Myr Welder. Something like Dimir Guildmage or Snapcaster Mage but at . Snapcaster Mage fills that slot for the slot, because in a non infinite scenario he's good, but with infinite mana if I hit him with a coco, he can give coco flashback and then dig for more creatures, like another snapcaster or superions. Trinket Mage did that for The Architect of Oz but I am trying to move away from small artifacts since the point of this deck is to be more creature based and to move away from small artifacts so as not to get blown out by Stony Silence. While it isn't fool-proof against Stony Silence, my initial idea is to cut the staff, add Walking Archive as a one of mainboard, and then maybe add a Blue Sun's Zenith back into the main-board. Not sure I like this though. In fact I'm almost sure there is something better out there, but I don't have the time tonight to find it. That or I could just add BSZ back mainboard but again, I am sure there is a better alternative out there. I just have to find it.

Birds of Paradise as possible consideration. Synergy with superion. Mana fixing. Consider over mainboard skites and a land.

Note to self: Sultai variant of Pili-Pala deck inferior to other color combos. Not to be further explored. Deck being changed to bant.

OKAY I AM FREAKING OUT OVER THIS DECK!!!
Eternal Witness = dorothy
Spellskite = todo
Qasali Pridemage = cowardly lion
Myr Superion = tin man
Grand Architect = wizard of oz
Pili-Pala = scarecrow
and now dorothy can Glittering Wish for no place like home! GAH! THE VORTHOS PERFECTION COMBINED WITH RAW COMPETITIVE POWER!!! WHY HAVE I NOT BUILT THIS SOONER?!?!

Ok so I really need help with the wishboard here. I don't think the main-board is going to change that much, but multi-colored cards that are great in certain match-ups... the list is a long one. So that is my focus for THIS variant, for now.

Also from a few playtests, I think I might want to try to go down to 2 Glittering Wishs. Yeah they are nice and provide me with a lot of tech options in the sideboard, but I really am not liking how flooded i tend to get on muddles and wishes. It's too great of a tempo loss for some increase in consistency, and I think that I should be ok with just two. Or I can do a 3/3 split between it and muddle. Still, something to think about for anyone wanting to leave feedback.

Trying to fit Immortal Servitude into the wishboard. Thinking about dropping leylines to make room for some more anti-control tech. That might be unwise given that jund/junk are still decks though. Leyline not only eats their forced discard, but stops Liliana of the Veil.
Restore the Peace is an interesting, cheaper version of Supreme Verdict that might fill one of the three leyline slots. As far as board clears go though, it's not anything special.
