Activate a permanent by tapping it, adding at least .
Cast Ghostly Flicker by paying due to Hinata, blinking Ardent Elementalist and the permanent tapped for mana in step 1.
When Ardent Elementalist enters the battlefield, it triggers, returning Ghostly Flicker from your graveyard to your hand.
Repeat.
This loop relies on the clever cost-reduction mechanic of Hinata, Dawn-Crowned, which slashes the price of Ghostly Flicker by {2} because it targets two separate permanents you control. You use that discount to target both Ardent Elementalist and a mana-producing permanent, allowing Ghostly Flicker to be cast for just a single blue mana. When Ardent Elementalist hits the battlefield, its triggered ability plucks Ghostly Flicker right back out of your graveyard, setting you up to repeat the entire sequence indefinitely for infinite value.
