Dour Port-Mage + Walk the Aeons + Donnie & April, Adorkable Duo

Dour Port-Mage

Walk the Aeons

Donnie & April, Adorkable Duo

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 Donnie & April by paying its mana cost.
3. When Donnie & April 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 Donnie & April from the battlefield to your hand.
6. Dour Port-Mage triggers, causing you to draw a card.
7. Repeat.

This clever loop centers on endlessly chaining extra turns by recycling Walk the Aeons from your graveyard back to your hand using the enter-the-battlefield ability of Donnie & April, Adorkable Duo. To reset Donnie & April and repeat the process, you use Dour Port-Mage's active ability to bounce the Duo back to your hand, which conveniently triggers the Mage's passive draw ability to keep your hand full of resources. By constantly replaying Donnie & April to fetch back your extra-turn spell and using the Port-Mage to loop it all, you generate an unstoppable sequence of infinite turns and card advantage.
