So here's a Dimir tutelage deck that's been working very well for me. Having played a ton of games with sultai turbofog, I wanted something faster and decided to aim for a more consistent manabase with some fun interactions. It's also a lower curve and I feel more solid vs aggro with a bunch of early drops. Only played a few tutelage mirrors, yet I think it's slighlty better with more draw options than a sultai fog typically runs.

Mortuary MireAltar's reap has been fanstastic and I'd like to go to 3, just held back by the thought of 2+ in my hand with nothing to sac. Altar's reap on Myr for instant speed damage shenanigans is often unexpected and can win games by itself. If you're playing a naked fleshbag, you can also reap with the fleshbag effect on the stack.
Some flex spots are the 2 counters and liliana. The counters might have been a tilt-induced response to a few too many turn 4 Moss, but also served well as tutelage protection. Never used the Awaken on Scatter, just wanted a no nonsense counter for late game, with spell shrivel removing the strain of UU on turn 3, undecided which is better.
Liliana sometimes feels a bit "win-more" in that early game you usually have better things to do with your mana to follow your game-plan, and late-game you want to be digging as much as possible. That said, she's a powerhouse left unchecked and the discard works well with all the draw in the deck, as well as bringing back fleshbags/myrs/drones. Dodging removal through Altar's reap is also fun!
Mortuary Mire was an afterthought, intended only for Jace really. Only used it once so far and I'm thinking of replacing with a basic land.
Notable omission is Possessed Skaab, which although a great card, I feel is just a bit too slow here. It's great for a 6 mana fog in Sultai but I think that's a function of fog being so cheap.
I'd also love to include an ulamog and a necromantic summons, which would be fun, but I'm not sure if it would improve consistency and speed which is what I was aiming for here after moving from sultai fog.
