Specimen Collector + Quasiduplicate + Altar of Dementia

Specimen Collector

Quasiduplicate

Altar of Dementia

How it works

1. Cast Quasiduplicate by paying 1, creating a token copy of Specimen Collector.
2. When the Specimen Collector token enters the battlefield, its first ability triggers, creating a 1/1 Squirrel and a 0/3 Crab creature token.
3. Activate Altar of Dementia by sacrificing the nontoken Specimen Collector.
4. When Specimen Collector dies, its second ability triggers, creating a token copy of the Specimen Collector token.
5. Repeat from step 2.
6. Resolve all Altar of Dementia abilities, causing any number of players to mill infinite cards.

This clever loop turns Specimen Collector into an endless replication engine by leveraging Quasiduplicate to seed the battlefield with a copy that triggers fresh creature tokens upon arrival. Whenever you need to fuel the chain, Altar of Dementia provides the necessary sacrifice outlet to bin a creature while weaponizing its power to mill away your opponents' libraries. As each original Specimen Collector perishes, its own death trigger steps in to recreate the copy cycle anew, letting you loop the entire sequence indefinitely for infinite tokens, deaths, and self-mill.
