Flash, Protean Hulk, Spellseeker, Thassa's Oracle, Blood Pet, and Demonic Consultation

Prerequisites

• Flash in hand
• Protean Hulk in hand
• Spellseeker in hand
• Thassa's Oracle in hand
• Blood Pet in hand
• Demonic Consultation in hand

Steps

1. Cast Flash, targeting Protean Hulk
2. Protean Hulk dies on ETB, fetching Blood Pet, Spellseeker, and Thassa's Oracle
3. Arrange the stack such that Spellseeker's trigger is on top, so that when it resolves, it fetches Demonic Consultation
4. Cast Demonic Consultation by sacrificing Blood Pet, adding 1 black mana to your mana pool
5. Make sure Demonic Consultation targets a card not in your library, causing you to exile your entire library
6. Then, Thassa's Oracle ETB resolves, and since you have no library, you win the game

Results

• Exile your library
• Win the game
