Zur the Enchanter + Second Chance + Tel-Jilad Stylus

Zur the Enchanter

Second Chance

Tel-Jilad Stylus

How it works

1. At the beginning of your upkeep, Second Chance triggers.
2. Holding priority, activate Tel-Jilad Stylus by tapping it, putting Second Chance on the bottom of your library from the battlefield.
3. Resolve the Second Chance trigger, causing you to take an extra turn after this one.
4. Declare Zur as an attacker.
5. Zur triggers, searching your library for Second Chance and putting it onto the battlefield.
6. Repeat each turn.
