This elegant loop revolves around Ghostly Flicker targeting Mnemonic Wall and a mana-producing permanent, allowing the Wall's entry trigger to fish the spell right back out of your graveyard while refunding the mana to do it all over again. Mindsplice Apparatus serves as the ultimate engine enabler here, passively discounting your instant and sorcery spells as it accumulates oil counters during each of your upkeeps. By drastically lowering the mana burden of Ghostly Flicker, Mindsplice Apparatus makes the entire recursive sequence dramatically easier to sustain, transforming an ordinary blink effect into an infinite storm and magecraft engine.
