Mortuary + Woe Strider + Crookshank Kobolds + Gwenom, Remorseless

Mortuary

Woe Strider

Crookshank Kobolds

Gwenom, Remorseless

How it works

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

This loop relies on Woe Strider's sacrifice outlet to constantly bin your creatures, while Mortuary steps in to redirect those fallen cards straight back to the top of your library. Because Crookshank Kobolds costs zero mana to cast, it serves as the ultimate recursive fuel, letting you cycle the same creature through the graveyard indefinitely. Meanwhile, Gwenom, Remorseless capitalizes on this endless rotation by letting you cast that zero-mana card right off the top of your library while paying life instead of mana costs—though in this case, a zero-mana value means you pay absolutely nothing.
