Rionya, Fire Dancer + Dockside Extortionist + Hellkite Charger

Rionya, Fire Dancer

Dockside Extortionist

Hellkite Charger

How it works

1. At the beginning of your combat phase, Rionya triggers, creating at least one token copy of Docksdie Extortionist with haste.
2. When the Dockside Extortionist token(s) enter the battlefield, they trigger, creating at least seven Treasure tokens.
3. Declare Hellkite Charger as an attacker, triggering its ability.
4. Holding priority, activate seven Treasure tokens by tapping and sacrificing them, adding 5.
5. Resolve the Hellkite Charger trigger from step 3, causing you to pay 5 to untap all attacking creatures you control and to get an additional combat phase after this one.
6. Repeat each combat phase.

This explosive loop relies on Rionya, Fire Dancer multiplying your resources the moment combat begins by churning out hasty token copies of Dockside Extortionist. As those shiny new goblins flood the battlefield, they harvest a massive pile of Treasure tokens from your opponents' artifacts and enchantments, feeding the mana requirement needed to keep the engine roaring. You then declare Hellkite Charger as an attacker, leveraging its ability to grant you repeated extra combat phases by paying the very mana your cloned Extortionists just generated. Because Rionya triggers afresh at the start of every single combat step, you can continually rebuild your army and outpace any opponent until the game is won.
