Long Feng, Grand Secretariat + Moss-Pit Skeleton + Verdant Succession + Phantom Train

Long Feng, Grand Secretariat

Moss-Pit Skeleton

Verdant Succession

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Moss-Pit Skeleton.
2. When Moss-Pit Skeleton dies, Long Feng and Verdant Succession trigger.
3. Resolve the Long Feng trigger, putting a +1/+1 counter on a creature you control.
4. Moss-Pit Skeleton triggers, putting itself from your graveyard onto the top of your library.
5. Resolve the Verdant Succession trigger, searching your library for Moss-Pit Skeleton and putting it onto the battlefield.
6. Resolve the Phantom Train ability.
7. Repeat.

This loop turns Phantom Train into a meat grinder by using its ability to continuously sacrifice Moss-Pit Skeleton, feeding a recursive engine built around Long Feng, Grand Secretariat and Verdant Succession. Whenever the Skeleton hits the graveyard, Long Feng places a +1/+1 counter that triggers Moss-Pit Skeleton's own ability from the graveyard, while Verdant Succession simultaneously fetches another copy straight from your library onto the battlefield. This allows you to cycle the same creature endlessly, generating boundless sacrifices, enter-the-battlefield triggers, and a mountain of +1/+1 counters.
