How it works
Cast Walk the Aeons by paying 4.
Double Vision triggers, copying Walk the Aeons.
Holding priority, cast Venser by paying 2.
When Venser enters the battlefield, it triggers twice, returning itself and the original Walk the Aeons to your hand from the battlefield and stack respectively.
Resolve the copy of Walk the Aeons, causing you to take an extra turn after this one.
