Quintorius Kand + Flicker + The Mirari Conjecture + Biblioplex Assistant

Quintorius Kand

Flicker

The Mirari Conjecture

Biblioplex Assistant

How it works

1. At the beginning of your precombat main phase, The Mirari Conjecture triggers, putting a lore counter on it, and then causing you to copy any instant or sorcery spell you cast this turn and sacrifice The Mirari Conjecture.
2. Cast Flicker by paying 1, targeting Biblioplex Assistant.
3. The Mirari Conjecture triggers, copying Flicker targeting Quintorius Kand.
4. Resolve the copy of Flicker, blinking Quintorius Kand.
5. Resolve the original Flicker, blinking Biblioplex Assistant.
6. When Biblioplex Assistant enters the battlefield, it triggers, putting Flicker on top of your library from your graveyard.
7. Activate Quintorius Kand's second loyalty ability by removing three loyalty counters from it, causing you to exile Flicker from the top of your library and cast it without paying its mana cost, targeting Biblioplex Assistant.
8. Quintorius Kand and The Mirari Conjecture trigger.
9. Resolve the Quintorius Kand trigger, dealing 2 damage to each opponent and causing you to gain 2 life.
10. Resolve the The Mirari Conjecture trigger, copying Flicker targeting Quintorius Kand.
11. Repeat from step 4.

This elegant loop turns a modest blink spell into a lethal engine by combining a few recursive tools. With The Mirari Conjecture's third lore counter active to copy your instant and sorcery spells, casting Flicker sets up a chain reaction that targets both Biblioplex Assistant and Quintorius Kand. Every time Biblioplex Assistant re-enters the battlefield, it conveniently tucks Flicker right back on top of your library where Quintorius Kand's discover ability can immediately exile and cast it for free. Meanwhile, Quintorius Kand triggers off every single one of those spells cast from exile to steadily drain your opponents out of the game while padding your own life total.
