Hellkite Charger + Savage Ventmaw + Druids' Repository

Hellkite Charger

Savage Ventmaw

Druids' Repository

How it works

1. Declare Hellkite Charger and Savage Ventmaw as attackers.Druids' Repository's first ability triggers twice, and Savage Ventmaw and Hellkite Charger trigger once.
2. Resolve the Savage Ventmaw trigger, adding .
3. Resolve both Druid's Repository triggers, putting two charge counters on it.
4. Activate Druid's Repository by removing a charge counter from it, adding 1.
5. Resolve the Hellkite Charger trigger, causing you to pay 5 to untap all attacking creatures and to get an additional combat phase after this one.
6. Repeat each combat phase.

This brutal dragon-fueled loop turns the simple act of attacking into an endless sequence of extra combat phases. As soon as Hellkite Charger and Savage Ventmaw charge into the red zone, the Ventmaw's ferocious attack trigger generously provides the exact six mana needed to fund the Charger's extra combat requirement. Meanwhile, Druids' Repository quietly tracks the assault, offering up the spare mana or charge counters needed to grease the wheels of your infinite turns.
