Mortuary + Woe Strider + Bolas's Citadel + Rograkh, Son of Rohgahh

Mortuary

Woe Strider

Bolas's Citadel

Rograkh, Son of Rohgahh

How it works

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

This brilliant loop transforms zero-mana commanders into an endless engine of sacrifice and spellcasting. With Bolas's Citadel sitting on your battlefield, you can gaze at the top of your library and cast spells directly from it by paying life instead of mana—making a free spell like Rograkh, Son of Rohgahh cost zero life to cast over and over. When Woe Strider sacrifices your legendary kobold, Mortuary catches it on its way to the graveyard and immediately tucks it right back onto the top of your library. Meanwhile, Woe Strider's presence also provides fodder like its initial Goat token if you need extra utility, while letting you scry through your library as the cycle endlessly repeats.
