God-Eternal Kefnet + Jace, the Mind Sculptor + Beacon of Tomorrows

God-Eternal Kefnet

Jace, the Mind Sculptor

Beacon of Tomorrows

How it works

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

By leveraging Jace, the Mind Sculptor's zero loyalty ability to stack Beacon of Tomorrows directly on top of your library, you ensure that your draw step perfectly sets up God-Eternal Kefnet's triggered ability. When you draw the beacon, Kefnet spots the revealed sorcery and generates a discounted copy that lets you take an extra turn. Because Beacon of Tomorrows includes a self-shuffling clause, casting the copy safely recycles the original back into your deck, leaving Jace ready to stack it once more for an unbroken loop of infinite turns.
