@nofuture I thought it cast enchantments, Well that's embarrassing.
Scholar doesn't really work with Omni, it only casts instant/sorcery/artifact and is a pretty inferior Show and Tell/thing to cast with Omni already in play.
@nofuture Somewhere on here is a scholar of the lost trove oath thread with omniscience a few of those would give you a real good target if you milled only a few cards before hitting scholar and make playing show and tell give you access to the whole had you just reloaded with for 0 mana.
Maybe something of a Combo Oath Shell with Scholar of the Lost Trove and a Tendrils kill. I think 1 Sphinx and 1 Griselbrand as targets.
Could also lean a little on fast mana and rituals to fuel your disruption (Thoughseize and maybe even Hymn powered out by Dark Rit.) as getting hellbent is not the worst when you are exchanging your graveyard for your hand.
I also imagine that Entomb as a tutor would be valuable as you can cast it on upkeep to make sure you have a critical combo piece and effectively choose which Oath target you want to hit by responding to your own Oath trigger .
An important question is if you will be able to effectively play Tinker-Citadel with 2 extra 7 mana spells in your deck.
My guess is that it would be hard to play more than the restricted blue package (no fow/preordains) to have enough room for rituals and other combo pieces.
I think about a list when I have a spare moment.
