Helm of the Host

How it works

1. At the beginning of your combat phase, Helm of the Host triggers, creating a nonlegendary token copy of Lonis.
2. Activate Grinding Station by tapping it and sacrificing a Clue.
3. Lonis and the Lonis token's second abilities trigger.
4. Resolve the nontoken Lonis trigger, putting a +1/+1 counter on the token Lonis.
5. The token Lonis's first ability triggers, creating a Clue artifact token.
6. When the Clue enters the battlefield, Grinding Station triggers, untapping Grinding Station.
7. Resolve the token Lonis's trigger from step 2, putting a +1/+1 counter on the nontoken Lonis.
8. The nontoken Lonis's first ability triggers, creating a Clue artifact token.
9. When the Clue enters the battlefield, Grinding Station triggers, untapping Grinding Station.
10. Resolve the Grinding Station ability.
11. Repeat from step 2.
