Brudiclad, Telchor Engineer + Timestream Navigator + Saheeli's Artistry

Brudiclad, Telchor Engineer

Timestream Navigator

Saheeli's Artistry

How it works

1. Cast Saheeli's Artistry by paying 4, creating a token copy of Timestream Navigator.
2. 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.
3. 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.
4. Move to your next turn.
5. Repeat from step 2.

This loop revolves around multiplying a single key permanent into an army that can rewrite time itself. First, you cast Saheeli's Artistry to forge a token copy of Timestream Navigator, setting the stage once you achieve the city's blessing. Then, as your combat phase begins, Brudiclad, Telchor Engineer swoops in: his passive grants your tokens haste, and his triggered ability lets you turn every single token you control into an exact copy of that Timestream Navigator token. Finally, you activate one of your newly minted Navigators, sending it to the bottom of your library to take an extra turn, only to repeat the whole process anew.
