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 Map artifact token.
Activate Krark-Clan Ironworks by sacrificing the Map 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 clever loop transforms a simple sacrifice into an engine that feeds upon itself, powered by Clan Crafter granting Lonis, Genetics Expert the ability to sacrifice artifacts to draw cards and grow. Because Worldwalker Helm multiplies your artifact token creation, every time Lonis triggers you get an extra Map token alongside your Clue, ensuring you always have spare fodder for Krark-Clan Ironworks to convert into the mana needed to keep the cycle going. As the Clues are sacrificed and replaced, Lonis cascades into infinite card draw, infinite draw triggers, and massive +1/+1 counters to overwhelm the table.
