How it works
Activate up to seven lands by tapping them, adding at least 2.
Cast Ghostly Flicker by paying 2, blinking Eternal Witness and Great Whale.
When Eternal Witness and Great Whale enter the battlefield, their abilities trigger.
Resolve the Eternal Witness trigger, returning Ghostly Flicker to your hand from your graveyard.
Resolve the Great Whale trigger, untapping up to seven lands.
Repeat.
If you control seven lands that can tap to produce at least 3, this combo nets infinite mana, and you may blink any other permanent besides Great Whale.
This elegant loop turns the mana-generating power of Great Whale into an engine of continuous recursion by looping Ghostly Flicker through the graveyard. Each iteration relies on Eternal Witness entering the battlefield alongside the whale, allowing you to pluck the very spell that just blinked them right back out of your graveyard and into your hand. Because Great Whale untaps up to seven lands upon its arrival, you easily generate a surplus of mana over the spell's cost, fueling an infinite cycle of blinks that can sweep up any other permanents you control along the way.
