This devious combination turns Koh, the Face Stealer into an absolute engine by leveraging its unique ability to borrow the text box of Asmodeus the Archfiend. Once Koh adopts Asmodeus's activated abilities—specifically the one that draws seven cards for three black mana—we need a way to fund that cost repeatedly. That’s where Mind Over Matter comes in, letting you pitch cards from your hand to untap your mana sources, converting your freshly drawn cards into the mana needed to keep the cycle spinning.
