How it works
Cast Rite of Replication by paying 2, creating a token copy of Timestream Navigator.
At the beginning of your combat phase, Brudiclad triggers, creating a 2/1 Phyrexian Myr creature token, then choosing to have all tokens you control become copies of the Timestream Navigator token.
Activate Timestream Navigator by paying 2 and tapping it and putting it onto the bottom of your library, causing you to take an extra turn after this one.
