Reaper King + Hostility + Atla Palani, Nest Tender + Maskwood Nexus

Reaper King

Hostility

Atla Palani, Nest Tender

Maskwood Nexus

How it works

1. Cause a creature to enter the battlefield under your control by any method.
2. When that creature enters the battlefield, Reaper King triggers, destroying that creature.
3. Resolve Atla Palani's trigger, revealing cards from the top of your library until you reveal a creature card and putting it onto the battlefield.
4. Repeat from step 2 until Hostility enters the battlefield then dies, or until you choose to end the loop by destroying an opponent's permanent.
5. If Hostility dies, it and Atla Palani trigger.
6. Resolve Hostility's trigger, shuffling it into your library.
7. Continue from step 3.

This mesmerizing loop turns Maskwood Nexus into the ultimate engine of identity transformation, making every creature you own count simultaneously as a Scarecrow, an Egg, and a Shaman. Atla Palani, Nest Tender provides the sacrificial spark by populating your board with Eggs, while Reaper King steps in to immediately destroy them—triggering a cascade of destruction for your opponents' permanents. Because Maskwood Nexus makes every creature you cheat out trigger Reaper King and Atla Palani alike, the engine sustains itself by continually flipping fresh threats from your library. Finally, Hostility ensures that if you cycle through your deck and it hits the graveyard, it simply shuffles right back in, keeping your infinite creature triggers spinning endlessly.
