Ghostly Flicker + Will Kenrith + Mnemonic Wall + Mana Geode

Ghostly Flicker

Will Kenrith

Mnemonic Wall

Mana Geode

How it works

1. Activate Will Kenrith's -2 ability targeting yourself, reducing the cost of your instant, sorcery, and planeswalker spells by 2 until end of turn and drawing you 2 cards.
2. Activate Mana Geode by tapping it, adding .
3. Cast Ghostly Flicker by paying , targeting Mana Geode and Mnemonic Wall, blinking them.
4. When Mnemonic Wall enters the battlefield, return Ghostly Flicker to you hand.
5. When Mana Geode enters the battlefield, scry 1.
6. Repeat.

This clever loop relies on Will Kenrith's minus ability to deeply discount your spells, allowing Ghostly Flicker to be cast for just a single blue mana. As Ghostly Flicker blinks both Mnemonic Wall and Mana Geode simultaneously, the Wall's entry triggers to return the Flicker right back to your hand while the Geode taps for the mana needed to repeat the process. This creates an endless cycle that endlessly triggers enters-the-battlefield effects, lets you scry your entire deck away with the Geode's scry, and racks up infinite storm and magecraft triggers.
