Brago, King Eternal + Cyclonic Rift + Eternal Witness

Brago, King Eternal

Cyclonic Rift

Eternal Witness

How it works

1. Cast Cyclonic Rift for its overload cost by paying 6, returning all nonland permanents you don't control to their owners' hands.
2. Deal combat damage using Brago, triggering its ability, blinking Eternal Witness.
3. When Eternal Witness enters, it triggers, returning Cyclonic Rift from your graveyard to your hand.
4. Repeat each turn.
