4/5 games are won by mill. 1/5 by attacking.
Current rank: Mythic 98%. Now playing with sideboard.
Rogues are here to steal your library. This is a competitive mill deck, but also a competitive Tempo deck with some amazing cards not normally seen in Dimir flash!
We will mill you, or beat you down, or both, depending on the matchup.
News: Ruin Crab is great. Stifles early aggro and can mill 15 cards by itself.
Draw Mill
Teferi's Tutelage Every card draw mills two, so:
Into the Story - 4 cards for 2UU is INSANE VALUE (and Mill 8 or 16 if you have tutelages, why not)
Slitherwisp - With all those rogues in our deck having flash, this also draws a bunch
Merfolk Windrobber - maybe i should play more of these.
Village Rites - strange card is pretty good here. When they move to kill your Wisp, you sac in response and get 2 more cards (and mill 4)
Rogue Mill
Thieves' Guild Enforcer and Soaring Thought-Thief can each get a good number of cards in the graveyard.
Removal
Drown in the Loch is absolutely nuts: Counter or kill anything for 2 mana.
Eliminate, Heartless Act, Brazen Borrower
Erebos's Intervention is useful for getting rid of bothersome Escape cards (Uro), though usually they don't matter much.
Game Plan
This is a tempo deck. It can win fast or win slow. An early mill card to enable Drown in the Loch is helpful. Just know what cards bother you, and be prepared for them.
Get the board under control then play tutelage. Draw cards when you need cards (lands, answers, etc).
Omnath: Favored? All their card draw suits us as we mill them out. Kill Omnath. Counter ultimatum. Attack when it suits you.
Control: Favored. You can win in the air or by milling, even if it's a Yorion deck. Use flash, be prepared to counter ECD or Ugin. Not much else matters.
Red Aggro: Play control. Removal, blockers, counter spells. Tutelage comes after you have control of the ground.
Cycling: Unfavored. Save your counterspells. Stop the aggro plan. Draw cards to get answers. Don't mill too early.
Adventures: Huge favorite. Don't attack. Don't dump a lot of creatures on the board into a Lucky Clover. Just mill hard and stop them from attacking.
Dimir Flash: Favorable. They don't have the card draw we have. Sculpt the game so you can resolve your Tutelage and card draw. Use removal and blockers to control the board.
UR Prowess: Easy Street! Bounce/kill any creature after pumps. Or if it's in your way. Or just attack into it because if they block, you have lots more creatures. Or mill them because they are drawing like crazy.
