Moss-Pit Skeleton + Chalk Outline + Cloakwood Swarmkeeper + Skyswimmer Koi

Moss-Pit Skeleton

Chalk Outline

Cloakwood Swarmkeeper

Skyswimmer Koi

How it works

1. Put a +1/+1 counter on a creature you control.
2. Moss-Pit Skeleton triggers, putting it from your graveyard onto the top of your library.
3. Chalk Outline triggers, creating a 2/2 Detective creature token and a Clue token.
4. When the Clue and Detective enter the battlefield, Skyswimmer Koi and Cloakwood Swarmkeeper trigger.
5. Resolve the Skyswimmer Koi trigger, drawing Moss-Pit Skeleton from your library, and then discarding it.
6. Resolve the Cloakwood Swarmkeeper trigger, putting a +1/+1 counter on it.
7. Repeat from step 2.

This clever loop turns the simple act of adding a counter into an endless cycle of creation and card-cycling, brilliantly orchestrated by Chalk Outline acting as the bridge between your graveyard and the battlefield. Whenever you pump up your board, Moss-Pit Skeleton effortlessly climbs from the graveyard right back to the top of your library, waiting to be drawn and discarded all over again. Skyswimmer Koi fuels this digging process by letting you instantly trade your newly drawn cards for the discarded skeleton, while Cloakwood Swarmkeeper steadily grows larger on the influx of fresh tokens. Every piece works in harmony to flood the board with Detective and Clue tokens, infinitely compounding your resources into an unstoppable army.
