Long Feng, Grand Secretariat + Moss-Pit Skeleton + Verdant Succession + Viscera Seer

Long Feng, Grand Secretariat

Moss-Pit Skeleton

Verdant Succession

Viscera Seer

How it works

1. Activate Viscera Seer 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 Viscera Seer ability.
7. Repeat.

This loop turns a simple sacrifice into a perpetual self-sustaining engine by uniting death triggers with library manipulation. When you use Viscera Seer to sacrifice Moss-Pit Skeleton, Verdant Succession lets you instantly fetch another copy of it straight from your library, while Long Feng, Grand Secretariat places a +1/+1 counter that immediately satisfies Moss-Pit Skeleton's own graveyard condition to place itself right back on top of your library for the next search. Because the card returns to the top of your deck just in time to be found again, you create an endless cycle of creature deaths, enters-the-battlefield events, and scry 1 triggers.
