Mortuary + Megatog + Memnite + Bolas's Citadel

Mortuary

Megatog

Memnite

Bolas's Citadel

How it works

1. Activate Megatog by sacrificing Memnite
2. When Memnite dies, Mortuary triggers, putting Memnite from your graveyard onto the top of your library.
3. Resolve the Megatog ability.
4. Cast Memnite from the top of your library by paying 0 life.
5. Repeat.

This clever loop transforms a humble zero-mana creature into an endless engine of growth and sacrifice. By using Bolas's Citadel to cast Memnite straight from the top of your library for free—since its mana value is zero—you can feed it directly to Megatog to pump its power and trample. Each time Memnite hits the graveyard, Mortuary instantly intercepts it and places it right back on top of your library, setting up the Citadel to cast it all over again.
