Saheeli, Radiant Creator + Brudiclad, Telchor Engineer + Lightning Runner

Saheeli, Radiant Creator

Brudiclad, Telchor Engineer

Lightning Runner

How it works

1. At the beginning of your combat phase, Brudiclad and Saheeli trigger.
2. Resolve the Saheeli trigger, causing you to pay EEE to create a token copy of Lightning Runner.
3. Resolve the Brudiclad trigger, creating a 2/1 Phyrexian Myr artifact token and then causing each token you control to become a copy of the Lightning Runner token.
4. Declare all Lightning Runners you control as attackers, triggering their abilities.
5. Resolve all but one Lightning Runner ability, causing you to get EE for each ability and choosing not to pay each time.
6. Resolve the final Lightning Runner ability, causing you to get EE and then pay eight E to untap all creatures you control and to get an additional combat phase after this one.
7. Move to your next combat phase. At the beginning of that phase, Saheeli and Brudiclad trigger.
8. Resolve the Saheeli trigger, choosing not to pay.
9. Repeat from step 3.
