Activate Lonis by paying 2 and sacrificing another artifact.
If the artifact was a Clue, Lonis' third ability triggers, putting a +1/+1 counter on any other creature you control.
Resolve the Lonis ability, putting a +1/+1 counter on it and causing you to draw a card.
Lonis' second ability triggers, creating a Clue and a Food artifact token.
Activate Krark-Clan Ironworks by sacrificing the Food or Clue, adding CC.
If the artifact was a Clue, Lonis' third ability triggers, putting a +1/+1 counter on any other creature you control.
Repeat.
This loop revolves around using Clan Crafter to grant Lonis, Genetics Expert an activation cost that feeds directly into Krark-Clan Ironworks, transforming artifacts into a self-sustaining engine. Every time you cycle a Clue or Food to the Ironworks for mana, Lonis and Peregrin Took work together to generate *more* tokens than you sacrifice, completely covering the activation cost while stacking up a massive storm of card draw, life gain, and +1/+1 counters. Peregrin Took is the linchpin that turns simple artifact cycling into a net-positive yield of Clues and Food, ensuring you never run out of fodder to feed the ironworks and keep the entire chain moving.
