Extravagant Replication + Scholar of the Ages + Walk the Aeons Combo

Walk the Aeons in hand.

Extravagant Replication and Scholar of the Ages on the battlefield.

You have enough mana to cast Walk the Aeons each turn.

Cast Walk the Aeons by paying its mana cost, causing you to take an extra turn after this one.

Move to your next turn.

At the beginning of your upkeep, Extravagant Replication triggers, creating a token copy of Scholar of the Ages.

When the Scholar of the Ages token enters the battlefield, it triggers, returning Walk the Aeons from your graveyard to your hand.

Repeat.
