Dour Port-Mage + Vampire Charmseeker + Walk the Aeons

Dour Port-Mage

Vampire Charmseeker

Walk the Aeons

How it works

1. Cast Walk the Aeons by paying its mana cost, causing you to take an extra turn after this one.
2. Cast Vampire Charmseeker by paying its mana cost.
3. When Vampire Charmseeker enters the battlefield, it triggers, returning Walk the Aeons from your graveyard to your hand.
4. Move to your next turn.
5. Activate Dour Port-Mage by paying 1 and tapping it, returning Vampire Charmseeker from the battlefield to your hand.
6. Dour Port-Mage triggers, causing you to draw a card.
7. Repeat.

By leveraging Dour Port-Mage's activated ability, you can repeatedly bounce Vampire Charmseeker back to your hand for just one mana and a tap, turning its enter-the-battlefield trigger into a recurring engine that continuously returns Walk the Aeons from your graveyard to your hand. Each time Vampire Charmseeker leaves the battlefield without dying to feed the loop, Dour Port-Mage's passive triggered ability rewards your efforts by drawing you a card. Because Walk the Aeons lets you take extra turns, you can easily untap, replay your spells, and sustain this infinite loop to lock down the game.
