Dimir Bounce

Dimir Bounce is one of the closest things Pioneer has to a prison deck. It creates an engine by bouncing many “enter the battlefield” (etb) effects that often draw cards, make the opponent discard cards, act as removal, or create tokens.

• A Thoughtseize deck with the backup of Hopeless Nightmare and Momentum Breaker to cause more discard.
• Breaker, Nowhere to Run, and Fatal Push serve as removal.
• Cryogen Relic and Narset, Parter of Veils for card advantage. Narset also keeps the opponent from getting their hand size back up.
• Stormchaser's Talent is huge in the deck, creating many otters that you easily make big from prowess and looping your bounce spells with level 2. The otters and the lifeloss from Hopeless provide a deceivingly fast clock. Leave your opponent handless and boardless while you drown in a fistful of value.
• Boomerang Basics can recur any of your permanents to use again and draw a card. This Town Ain't Big Enough often recurs two of your etb effects or one of yours and an opponent's to often time walk them. The bounce + discard also gives Dimir a rare way to deal with all permanent types.

Lastly, with Yorion, Sky Nomad as the companion, you can often threaten a Mind Twist + Board Wipe + Ancestral Recall in addition to a 4/5 flying threat. - Viperfang
