How it works
Activate Emiel the Blessed by paying 3, blinking Drowner of Hope.
When Drowner of Hope enters the battlefield, it triggers, creating two 1/1 Eldrazi Scion creature tokens.
Activate the Eldrazi Scions by tapping them, adding 2.
Activate an Eldrazi Scion by sacrificing it, adding C.
Repeat.
Once you have infinite tapped Eldrazi Scion tokens, you may sacrifice them for infinite C, and then forego tapping or sacrificing subsequent Eldrazi Scions.
