How it works

1. Activate Sophia by paying 1 and sacrificing an artifact token.
2. If the token was a Clue, Lonis's second ability triggers, putting a +1/+1 counter on a creature you control.
3. Resolve the Sophia ability, putting a +1/+1 counter on each creature you control.
4. Lonis's first ability triggers, creating a Clue token.
5. Activate Crystalline Crawler by removing a +1/+1 counter from it, adding 1.
6. Repeat.
