God-Eternal Kefnet + Jace, the Mind Sculptor + Walk the Aeons

God-Eternal Kefnet

Jace, the Mind Sculptor

Walk the Aeons

How it works

1. Activate Jace's zero loyalty ability, putting Walk the Aeons on top of your library.
2. Move to your next turn.
3. On your next draw step, when you draw Walk the Aeons, reveal it due to Kefnet's ability, making a copy that costs 2 less to cast.
4. Cast the copy for 2, granting you an extra turn.
