Ghostly Flicker + Mystic Sanctuary + The Great Henge + Future Sight

Ghostly Flicker

Mystic Sanctuary

The Great Henge

Future Sight

How it works

1. Activate Mystic Sanctuary and The Great Henge by tapping them, adding and causing you to gain 2 life.
2. Cast Ghostly Flicker either from your hand or from the top of your library by paying 2, blinking Mystic Sanctuary and The Great Henge.
3. When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
4. Repeat.

This clever loop achieves infinity by constantly recycling a single copy of Ghostly Flicker through the aid of Mystic Sanctuary, which uses its triggered ability to place the instant right back on top of your library each time it enters untapped. From there, Future Sight lets you play directly from the top of your deck, casting Ghostly Flicker anew to blink both the Sanctuary and The Great Henge. Meanwhile, The Great Henge acts as the ultimate engine for the loop, not only fueling the necessary mana and padding your life total with every iteration, but also taking advantage of the repeated artifact entries to draw your entire library.
