Sewer Nemesis

Kitsune's Technique

How it works

1. Cast Kitsune's Technique by paying its mana cost, causing the opponent named by Sewer Nemesis to mill half their library, rounded up.
2. Activate Sewer Nemesis by tapping it, causing the opponent to mill cards equal to the cards in their graveyard, milling the remainder of their library.
