Grinding Station + Underworld Breach
Overview
Underworld Breach lets you cast Grinding Station from your graveyard by paying its mana cost and exiling three other cards from your graveyard (the escape cost printed on Underworld Breach). When Grinding Station resolves as a permanent spell it becomes an artifact on the battlefield . You can then activate Grinding Station’s ability by tapping it and sacrificing an artifact — you may legally sacrifice Grinding Station itself as the sacrificed artifact when paying that ability’s costs. The ability mills three cards when it resolves; those three milled cards can be the “three other cards” you exile to pay Grinding Station’s next escape cost, letting you recur Grinding Station repeatedly as long as you can pay its mana cost each time and Underworld Breach remains available to provide escape .
