Here's a deck I've been running with some success. It's reasonable against the meta though it does rely quite a bit on the sideboard in some matchups so you sometimes need to win games 2 and 3 and not get mana screwed. Can go for self-mill win in control matchups if needed, very weak to Narset so that should be a priority discard. Agonizing Remorse is very good against most of the meta but awful vs RDW so it's a 3-1 split in the main, plus the surveil is good for finding lands, but remorse is much better against everyone else. Sideboard is very straightforward - more discard+unmoored+distortion makes control decks cry (unmoored should typically just take Dream Trawler). Not a T1 deck, but it's doing ok in diamond atm. Was running 0 Jace/2 Tamiyo and that setup is better at getting titans out, but I've won a fair amount of game 1s vs control via self-mill, maybe Tamiyo is still correct though.

MTGA import


There's a version with Nissa that looks good, though I think that card is significantly worse than it was in this Elspeth world.
