Phantom Steed

Walk the Aeons

Scholar of the Ages

How it works

1. Cast Walk the Aeons, taking an extra turn after this one.
2. Attack with Phantom Steed.
3. Phantom Steed triggers, creating a token copy of Scholar of the Ages that is tapped and attacking.
4. Scholar of the Ages enters, returning Walk the Aeons from your graveyard to your hand.
5. Pass the turn.
6. Repeat.
