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

God-Eternal Kefnet

Jace, the Mind Sculptor

Time Walk

How it works

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

This elegant Vintage loop locks down the game by chaining endless extra turns using just three key pieces. Jace, the Mind Sculptor sets up the top of your library each cycle with its zero ability, ensuring Time Walk is always waiting for your next draw step. When that draw happens, God-Eternal Kefnet triggers off the revealed Time Walk, letting you cast a discounted copy for just {U} to take another turn—while the original Time Walk safely returns to the deck to repeat the cycle indefinitely.
