Activate Joo Dee by paying and tapping it, causing you to surveil 1 and then create a token copy of Joo Dee and sacrifice the tapped Joo Dee.
When the tapped Joo Dee dies, Pitiless Plunderer triggers, creating a Treasure token.
Activate the Treasure by tapping and sacrificing it, adding .
Repeat using the Joo Dee token.
This clever loop turns a simple self-replication trick into a self-sustaining engine by letting Pitiless Plunderer turn every sacrifice into a fresh fuel source. Whenever Joo Dee, One of Many sacrifices itself to copy, the resulting death triggers the Plunderer to drop a Treasure token. You can immediately crack that Treasure for black mana to pay for the next activation, bypassing the usual speed restrictions thanks to Shang-Chi, Master of Kung Fu. Shang-Chi not only grants the necessary haste-like activation speed so you can immediately repeat the process, but its mana-producing ability can also help kickstart the entire chain.
