Inspirit, Flagship Vessel

Magistrate's Scepter

Vedalken Infuser

How it works

1. At the beginning of your upkeep, Vedalken Infuser triggers, putting a charge counter on Magistrate's Scepter.
2. At the beginning of your combat phase, Inspirit triggers, putting two charge counters on Magistrate's Scepter.
3. Activate Magistrate's Scepter's second ability by tapping it and removing three charge counters from it, causing you to take an extra turn after this one.
4. Repeat each turn.
