Built to abuse the stack and Evoke mechanic. A bit of a slow start with no one drops and only Wall of Omens as a 2 drop but hear me out here... Sundial of the Infinite after paying Evoke or flicker the creature to double the benefit and keep the creature in play. Draw many with Wall of Omens or bounce their perms with AEthersnipe.
Note: you'll never pay full cost for AEthersnipe or Mulldrifter. Always Evoke cost then Sundial of the Infinite, Bounce/flicker or let it die and Imprint it on the Mimic Vat.
Classic fiendhunter trick...
Play him but before the Exile trigger resolves, flicker him (Cloudshift or Essence flux). The first exile trigger is on the stack then the flicker. Flicker resolves first bringing fiendhunter back into play creating a 2nd exile trigger, then both those exile triggers resolve. The first (top) one is tied to the fiendhunter in play so when it leaves the Battlefield they get their creature back. The 2nd exile trigger is not tied to any creature in play so it's exiled forever.
Or just return fiendhunter to your hand (Unsommon or Saving Grasp) and immediately Sundial of the Infinite to end the turn now and exile their creature forever.
Same trick works with Leonin Relic-Warder because "may exile". Sideboard this in if you're playing vs. some artifact or enchantment deck.
Mimic Vat... Evoke a creature for the rewards (draw 2 or bounce), let it die. Imprint on Mimic Vat then do it with Haste once per turn. (Sundial of the Infinite to keep the token in play. see below)
Sundial of the Infinite... The usual Sundial tricks. Its all about when to play it. If you played a creature off of Mimic Vat and you sundial before the End Step the sac trigger dissolves and you keep said token. If you bounce a fiendhunter, Sundial of the Infinite before their "return exiled creature to the battlefield" trigger resolves
Detention Sphere +sideboard' shuts down tokens. Return it to your hand with AEthersnipe and do it again.
Stonehorn Dignitary shuts down their attack. Can we get it him on Sundial of the Infinite.
Flickerwisp should have a place in here. Target your fiendhunter then Sundial of the Infinite. They lose their creature then at the beginning of their endstep fiendhunter returns to exile another creature.
Still working on Sideboard. It's mostly a casual fun deck.
