The 3 combo pieces

What must be in place

Helm of the Host attached to Dockside Extortionist.
Opponents control at least seven artifacts and/or enchantments.
An opponent cannot block and kill Hellkite Charger.

How to execute it

  1. At the beginning of your combat phase, Helm of the Host triggers, creating a token copy of Dockside Extortionist with haste.
  2. When the token Dockside Extortionist enters the battlefield, it triggers, creating at least seven Treasure artifact tokens.
  3. Declare Hellkite Charger as an attacker, triggering its ability.
  4. Holding priority, activate seven Treasures by tapping and sacrificing them, adding {5}{R}{R}.
  5. Resolve the Hellkite Charger trigger, causing you to pay {5}{R}{R} to untap all attacking creatures you control and get an additional combat phase after this one.
  6. Repeat each combat phase.
  7. If opponents control at least eight artifacts and/or enchantments, this combo nets infinite Treasure tokens and colored mana.
