Brudiclad, Telchor Engineer + Lightning Runner + Rite of Replication

Brudiclad, Telchor Engineer

Lightning Runner

Rite of Replication

How it works

1. Cast Rite of Replication kicked from your hand, targeting Lightning Runner.
2. Create 5 token copies of Lightning Runner.
3. Move to combat, triggering Brudiclad to make a 2/1 Phyrexian Myr, then turn all tokens into Lightning Runner.
4. Attack with at least 4 Lightning Runners, creating 2 Energy for each Lightning Runner that attacked.
5. Pay 8 Energy into one of the Lightning Runners, creating an extra combat step and untapping all creatures you control.
6. Repeat steps 3-5.
