Inverter of Truth + Thassa's Oracle + Titans' Nest

Inverter of Truth

Thassa's Oracle

Titans' Nest

How it works

1. Activate Titan's Nest by exiling a card from your graveyard, adding C that can only be spent to cast a colored spell that does not have X in its mana cost.
2. Repeat step 1 until you have an empty library.
3. Cast Inverter of Truth by paying 2.
4. When Inverter of Truth enters the battlefield, it triggers, exiling your library.
5. Cast Thassa's Oracle by paying .
6. When Thassa's Oracle enters the battlefield, it triggers, causing you to win the game.

This clever synergy lets you hollow out your library to instantly secure a victory through alternate win conditions. By repeatedly activating Titans' Nest, you can exile every card from your graveyard to filter away your deck until nothing remains. Once your library is completely empty, you drop Inverter of Truth onto the battlefield; its enter-the-battlefield trigger finds no cards left in your library to exile or shuffle back, leaving you at absolute zero. Finally, casting Thassa's Oracle triggers its check on your devotion to blue, which instantly fulfills the condition that X is greater than or equal to the number of cards in your library to win the game on the spot.
