Found a fun little infinite in the cube while I was test drafting, and I was proud of it so I even put it on moxfield and wrote a little primer!
Primer below!
The beginning of the game you exile Savor the Moment for Arcane Savant, this will be the basis for our combo.
Due to the intentionally limited nature of Savor the Moment, we need to have ways to turn infinite turns, with Teleportation Circle and Savant, into a game winning combo.
Storm-Kiln Artist will net us 1 treasure a turn during the combo so we can still cast spells, this is the best case scenario since our lands don't untap during our additional turns, and Elixer of Immortality keeps us from drawing ourselves out.
Quintorious can make us 1 Spirit a turn so we have plenty to swing with, and you can us his -6 to generate mana for additional ways to end the game if necessary.
Young Pyromancer gives us 1 Elemental a turn that can hopefully end the game if our opponent has no blockers.
Chronozoa can slowly become a large mass of creatures that can swing in to end the game, but it is very slow so having an elixer on standby is probably important.
Reality Strobe can slowly clear the way so Savant can close out the game himself with his respectable 3/3 body.
Other cards are primarily for control to give us time to assemble the combo.
