Underworld Breach + Breaking // Entering + Lion's Eye Diamond

Underworld Breach

Breaking // Entering

Lion's Eye Diamond

How it works

1. Activate Lion's Eye Diamond by sacrificing it and discarding your hand, adding or .
2. Cast Breaking from your graveyard for its escape cost by paying and exiling three other cards from your graveyard, causing you to mill eight cards.
3. Cast Lion's Eye Diamond from your graveyard for its escape cost by paying 0 and exiling three other cards from your graveyard.
4. Repeat.

This vicious loop is anchored by Underworld Breach, which turns your graveyard into a second hand by granting every nonland card escape for its mana cost plus exiling three other cards. By cracking Lion's Eye Diamond for mana while discarding your hand, you fuel the exact resources needed to repeatedly cast Breaking // Entering from your graveyard via escape. As Breaking mills eight cards with every iteration, it continuously restocks your graveyard to pay the escape costs for both the sorcery and Lion's Eye Diamond, generating an unstoppable storm of self-mill and colored mana.
