4-card combo · U

Verdict

Yes — this 4-piece loop generates infinite storm, magecraft, and landfall triggers entirely within mono-blue, as long as three other Islands are on the battlefield.

Mystic Sanctuary's enters-the-battlefield trigger puts Ghostly Flicker back on top of the library each loop; Sol Ring and the Sanctuary itself produce the exact 2U to recast it, making the loop self-sustaining. Precognition Field lets the pilot cast Ghostly Flicker off the top of the library, which is what closes the engine — without it, the Flicker needs to be in hand to start and the loop doesn't cycle.

Recipe

How it works

Prerequisites

You control three additional Islands.

Steps

Activate Mystic Sanctuary and Sol Ring by tapping them, adding .
Cast Ghostly Flicker either from your hand or from the top of your library by paying , blinking Mystic Sanctuary and Sol Ring.
When Mystic Sanctuary enters untapped, it triggers, putting Ghostly Flicker from your graveyard onto the top of your library.
Repeat.

Result

Infinite storm count; Infinite magecraft triggers; Infinite landfall triggers

Variations

Cheaper, tighter, alternate lines

Archaeomancer or Salvager of Secrets can replace Mystic Sanctuary's recursion role by returning Ghostly Flicker to hand directly, though both require blinking a creature rather than a land and Sol Ring. The loop produces no mana beyond what it consumes, so pair it with Aetherflux Reservoir for the kill — Altar of the Brood converts the infinite landfall triggers into a mill win if the storm count kill feels fragile.
