Auramancer + Second Chance + Deadeye Navigator

Auramancer

Second Chance

Deadeye Navigator

How it works

1. At the beginning of your upkeep, Second Chance triggers, causing you to sacrifice it and take an extra turh after this one.
2. Activate Auramancer by paying 1, blinking itself.
3. Auramancer enters the battlefield, triggering itself and Deadeye Navigator's soulbond ability.
4. Resolve the Deadeye Navigator trigger, repairing it and Auramancer.
5. Resolve the Auramancer trigger, returning Second Chance from your graveyard to your hand.
6. Cast Second Chance by paying 2.
7. Repeat each turn.
