Underworld Breach + Malevolent Rumble + Citanul Hierophants + Thousand-Year Elixir

Underworld Breach

Malevolent Rumble

Citanul Hierophants

Thousand-Year Elixir

How it works

1. Cast Malevolent Rumble for its escape cost by paying 1 and exiling three other cards from your graveyard, causing you to mill at least three cards and create a 0/1 Eldrazi Spawn creature token.
2. Activate the Eldrazi Spawn by tapping it, adding .
3. Activate the Eldrazi Spawn by sacrificing it, adding C.
4. Repeat.

This clever loop turns Underworld Breach into a recursive engine by giving Malevolent Rumble the escape ability to continuously reload your graveyard. As you cast and recast the sorcery, Malevolent Rumble fuels itself by dumping cards into your graveyard while churning out Eldrazi Spawn tokens. To convert those tokens into the mana needed to keep casting, Citanul Hierophants grants your creatures a green mana ability, while Thousand-Year Elixir lets you untap them and bypass summoning sickness so they can immediately tap for mana and feed the combo.
