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

God-Eternal Kefnet

Jace, the Mind Sculptor

Time Warp

How it works

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

This elegant engine locks down the game by feeding you an endless succession of extra turns. With Jace, the Mind Sculptor safely sitting on your battlefield, you can use his zero-loyalty ability to stack Time Warp directly onto the top of your library. When you move to your next turn, God-Eternal Kefnet lets you reveal that newly drawn sorcery card right as you draw it, triggering a discounted copy that you immediately cast to take another turn. As you repeat this loop, Jace keeps tucking Time Warp back on top while Kefnet ensures you never run out of temporal momentum.
