Abyssal Tutelage (Turbo Mill) - 2021 version

Basically it's Peer into the Abyss-Teferi's Tutelage combo, BUT with a lot more efficiency built in. The name was a homage to Demonic Tutor , FYI.

1) Turn 1 : Ruin Crab, or start cycling to find pieces. <-- bit improvement instead of drop land-go for most other mills 

2) Just play your own game and occasionally take a few hits before blocking with apprentice. It works well as a 1/2 (stopping the 1/1 aggro's like fervent champions)

3) All you need is one tutelage and peer to randomly win. I have opted for a bit more control build from turn 2 onwards to take out early threats then drop tutelage and peer for the win. 

4) This is ok as a BO1 deck, but found that after boarding BO3 works better. The main deck version is pretty much the most direct/combo searching version. The board brings in additional delays and protections against the opponent deck.

5) The deck pretty much runs at instant speed, minus the Apprentice (when you have spare mana) and the combo pieces (Teferi's Tutelage/Peer into the Abyss)

This is the post-rotation version - with only main loss being Watery Graves. I have however attempted to update it for the meta which is now flooded with Clerics, Omnaths, and some Rogues.

Play Tips:

1) Big tip: When Teferi's Tutelage comes out, if there's no Frantic Inventory in grave, drop one into the grave. The 'conversion rate' is about 1 mana per card (cycle). The first Frantic Inventory is 2 mana for 1 card (not worth it), but once it's discsarded, the second one is immediately 1:1 mana/card for mill. 

2) Play 'control style', pretty much cycle (preference)/counter(if threat) on opponent's turn. After about 3 turns after Teferi's Tutelage, Into the Story becomes 4 mana:4 cards.. if they don't play anything. Good hand refill, mill and draw more counter/threats. 

3) If you have no cycle in starting hand, I tend to mulligan (unless you have tutelage).

4) The deck combos off at 7 land (3 swamps). Once you have the Peer/Tutelage combo, you just win :) It will be rare that you have that much less cards than half the opponent. Check before combo'ing anyway.

5) Pre sideboard, the deck can survive on a 1 land hand opening (if have cyclers/opt)

Sideboard:

Matchups:

UG-mutate mill:

UG mutate mill has a one drop crab turn 1 which is a pain on the draw, however it can stablize as they don't pack counter magic. Drowned will eventually catch up to them. They do run cacophany (keep Didn't say Please) for game 2. Board out 4 cycles, and brought in a few more cheap hates (Heartless) and Mystical Dispute

Expected rating:

I was able to get to Plat 2 in Sep. Since rotation it's hard to tell how far this deck will go. I think it's still the most stable mill deck in the format. not the most explosive/risky/unstable - but the slow/steady method. 

Changes:

 * While Overwhelmed Apprentice was better overall, I've moved it to Ruin Crabs for a bit more aggressive milling. the 1/2 body which was good to deal with X/1 aggro creatures. Scry gets you deeper into combo as well. But the meta seemed to prefer slightly more aggressive Ruin Crab
