How it works
Cast Quantum Misalignment by paying its mana cost, creating a token copy of Lonis that isn't legendary.
Activate Sarcatog by sacrificing a Clue.
Lonis and the Lonis token's second abilities trigger.
Resolve the nontoken Lonis trigger, putting a +1/+1 counter on the token Lonis.
The token Lonis's first ability triggers, creating a Clue artifact token.
Resolve the token Lonis's trigger from step 2, putting a +1/+1 counter on the nontoken Lonis.
The nontoken Lonis's first ability triggers, creating a Clue artifact token.
Resolve the Sarcatog ability.
Repeat from step 2.
This clever loop transforms a single sacrifice into an escalating cascade of Clues and counters by exploiting the interaction between a pair of legendary investigators. With a copy of Lonis, Genetics Expert on the field thanks to Quantum Misalignment, sacrificing a single artifact to Sarcatog triggers both Lonis and its double to investigate; each Clue creation feeds back into the other's triggered ability to distribute +1/+1 counters. Because placing those counters triggers each Lonis's evolve-like counter-placement ability to generate *more* Clues, Sarcatog's sacrifice cost is immediately refunded while pumping its own power to astronomical heights.
