Requires

Sphinx's Tutelage must be on the battlefield. Opposition Agent must be on the battlefield. Mana Severance must be in hand. Hive Mind must be on the battlefield. Painter's Servant must be on the battlefield. Any color chosen with Painter's Servant. Mana needed:

Steps

1. Cast Mana Severance by paying .
2. Hive Mind triggers, causing each opponent to copy Mana Severance.
3. Resolve each opponent's Mana Severance, exiling all lands from their libraries.
4. Resolve your Mana Severance, choosing not to exile any lands from your library.
5. The next time you draw a card, Sphinx's Tutelage triggers, causing an opponent to mill two cards.
6. Because Painter's Servant will force the cards to share a color, and they will not be lands due to the opponent having no lands in their library, Sphinx's Tutelage will continue to repeat the process until the opponent's library is empty.
