The 5 combo pieces

What must be in place

An opponent cannot block creatures you control.
You have at least {E}{E}{E}

How to execute it

  1. At the beginning of your combat phase, Saheeli triggers, causing you to pay {E}{E}{E} to create a token copy of Bloodthirster that is a 5/5 artifact creature with haste.
  2. When the Bloodthirster token enters the battlefield, Aetherstorm Roc, Decoction Module and Guide of Souls trigger, causing you to get {E}{E}{E} and gain 1 life.
  3. Deal combat damage using the Bloodthirster token. The token triggers, causing you to untap all creatures you control and to get an additional combat phase after this one.
  4. Repeat each combat phase.
