Walk the Aeons

How it works

1. Cast Walk the Aeons by paying its mana cost.
2. Kykar triggers, exiling Shipwreck Dowser.
3. Resolve Walk the Aeons, causing you to take an extra turn after this one.
4. At the beginning of your end step, Kykar triggers, returning Shipwreck Dowser from exile to the battlefield.
5. When Shipwreck Dowser enters, it triggers, returning Walk the Aeons from your graveyard to your hand.
6. Repeat each turn.
