Mnemonic Wall and Dockside Extortionist enter the battlefield, triggering their abilities.
Resolve the Dockside Extortionist trigger, creating at least six Treasure tokens.
Resolve the Mnemonic Wall trigger, returning Living Death from your graveyard to your hand.
Activate five Treasure tokens by tapping and sacrificing them, adding 3.
Repeat.
This brilliant loop hinges on casting Living Death while Chandra, Hope's Beacon and Displacer Kitten are safely in play to orchestrate a perpetual graveyard swap. When you cast your sorcery, Chandra copies it and Displacer Kitten blinks the planeswalker, allowing the copied Living Death to immediately sweep the board and resurrect your entire team—including Dockside Extortionist to flood you with Treasure tokens and Mnemonic Wall to pluck Living Death right back out of your graveyard. By sacrificing just a handful of those newly minted Treasures to pay the mana cost, you can repeat the entire cycle indefinitely for infinite resources and triggers.
