How it works
Activate Cogwork Assembler by paying 7, creating a token copy of Su-Chi Cave Guard with haste.
Activate Ashnod's Altar by sacrificing the Su-Chi Cave Guard token, adding CC.
When Su-Chi Cave Guard dies, it triggers, adding eight C.
Repeat.
Once you have infinite mana, you may repeat step 1 targeting any artifact you control.
This delightful loop turns the massive mana payoff of Su-Chi Cave Guard into an unstoppable engine. By leveraging Ashnod's Altar, you can sacrifice the token created by Cogwork Assembler for quick mana, which then triggers the dying creature to yield a surplus of eight colorless mana. With this profit, you can easily pay the steep activation cost to copy Su-Chi Cave Guard over and over again, eventually pivoting Cogwork Assembler's ability to duplicate any other artifact you desire.
