Vraska's Descent (Memory Flicker With Mill) [Standard] (Standard)

Concept, and Gameplan (Best case scenario that will only happen around 2.6% of the time):

I'll assume you play a land the first 4 turns.
I'll also assume you draw at least 5 lands, in your first 18 cards. (This is often the case.)

3. Play Psychic Corrosion
   • Opponent is milled for 2. (2 total)
4. Play Vraska, Golgari Queen
5. Use Vraska, Golgari Queen's first abillity, sacrifice a land, and draw a card.
   • Opponent is milled for 2. (4 total)
   • Opponent is milled for 2. (6 total)
6. Induced Amnesia yourself. (While you have another induced Amnesia in hand)
   • Opponent is milled for 12. (18 total)
   • Opponent is milled for 2. (20 total)
7. Use Vraska, Golgari Queen's first abillity, sacrifice Induced Amnesia, and draw a card.
   • Opponent is milled for 2. (22 total)
8. Induced Amnesia yourself.
   • Opponent is milled for 26. (48 total)

At the start of the opponent's next turn, they should lose the game.

The deck does function ok-ish even when just playing it as a slow control deck, trying to stay alive. Then milling the opponent's deck as described above.

If the game goes on too long, to the point where using this technique would kill you, you may use it on the opponent instead, make sure to always have multiple Induced Amnesia available, and you'll be forcing your opponent to draw an increasing number of cards. (playing Induced Amnesia, sac'ing it with Vraska, Golgari Queen, then Induced Amnesia again, forces them to draw cards equal to 3 times their hand size, which could cause them to deck out late in the game.)

Another Strategy to use in games that go on for very long, is to fetch Etrata, the Silencer from your sideboard, using Mastermind's Acquisition. With a small remaining deck, Etrata, the Silencer is easily able to be played multiple times, and could win you the game.

You can also fetch Muldrotha from the sideboard, to play Amnesia and Tragic Poet each turn.

As this is getting a bit too long now, for my taste, I'll stop here, and hope you'll figure the rest out yourselves.
