Remembrance + Deathrender + Arashin Sovereign + Shilgengar, Sire of Famine

Remembrance

Deathrender

Arashin Sovereign

Shilgengar, Sire of Famine

How it works

1. Activate Shilgengar by sacrificing Arashin Sovereign.
2. When Arashin Sovereign dies, it, Deathrender and Remembrance trigger.
3. Resolve the Arashin Sovereign trigger, causing you to put it on top of your library from your graveyard.
4. Resolve the Remembrance trigger, causing you to search your library for Arashin Sovereign and put it into your hand.
5. Resolve the Deathrender trigger, putting Arashin Sovereign from your hand onto the battlefield, and attaching Deathrender to it.
6. Resolve the Shilgengar ability
7. Repeat.

This loop centers around Shilgengar, Sire of Famine feeding our engine by sacrificing Arashin Sovereign, which conveniently generates a Blood token to help fund Shilgengar's massive graveyard-recursion ability. When Arashin Sovereign hits the graveyard, a trio of triggers fires off simultaneously: its own replacement effect, Deathrender's ability to cheat a creature straight from your hand, and Remembrance letting you tutor up a duplicate copy. By placing Arashin Sovereign on top of your library and immediately tutoring it back to your hand, Deathrender can then effortlessly re-equip to the newly deployed dragon to repeat the cycle.
