EDHREC #389 Theros Beyond Death
Two mana for a same-turn engine that lets you recast your whole graveyard is the kind of rate that warps deck-building decisions.
The line
Underworld Breach has been a fixture in cEDH and high-power Commander since Theros Beyond Death, and players keep asking how to break it. The answer is: pair it with something that fills the graveyard fast, because the card does all its work in a single turn window before it sacrifices itself at the beginning of the end step.
What it does
Every nonland card in your graveyard gets escape, meaning you can recast each one for its normal mana cost plus exiling three other cards from your graveyard. Chain enough cheap spells together with a full enough yard, and you're effectively replaying your entire deck. The enchantment sacrifices itself at the beginning of the end step, so the window is urgent but enormous within a single turn.
Where it shines
The flagship line is Breach plus Lion's Eye Diamond plus Brain Freeze, which mills your library, then closes with Thassa's Oracle. A second well-known line runs Breach with Lion's Eye Diamond and Wheel of Fortune for infinite looping that lets you dig to any win condition. Both show up in cEDH shells where the whole gameplan is assembling three cards and ending the game on the spot.
Plays well with
- Breach plus Lion's Eye Diamond plus Brain Freeze mills your entire library, and Thassa's Oracle then wins the game on the spot because your library is empty when it enters.
- Pairing Breach with Lion's Eye Diamond and Wheel of Fortune creates a loop where you keep recasting Wheel to refuel your graveyard and dig through your deck until you find your actual win condition.
- Breach plus Windfall plus Smothering Tithe generates infinite Treasures and card draw, because each wheel trigger forces opponents to pay or give you Treasures, which in turn funds recasting Windfall through Breach.
The catch
Graveyard hate completely dismantles it. A Leyline of the Void or a well-timed Rest in Peace leaves you holding a two-mana enchantment that does nothing. In metas where hate pieces are common, Breach becomes a liability rather than a threat.
