Quintorius Kand + Flicker + Swarm Intelligence + Mystic Sanctuary

Quintorius Kand

Flicker

Swarm Intelligence

Mystic Sanctuary

How it works

1. Cast Flicker by paying 1, targeting Mystic Sanctuary.
2. Swarm Intelligence triggers, copying Flicker targeting Quintorius Kand.
3. Resolve the copy of Flicker, blinking Quintorius Kand.
4. Resolve the original Flicker, blinking Mystic Sanctuary.
5. When Mystic Sanctuary enters the battlefield, it triggers, putting Flicker on top of your library from your graveyard.
6. 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 Mystic Sanctuary.
7. Quintorius Kand and Swarm Intelligence trigger.
8. Resolve the Quintorius Kand trigger, dealing 2 damage to each opponent and causing you to gain 2 life.
9. Resolve the Swarm Intelligence trigger, copying Flicker targeting Quintorius Kand.
10. Repeat from step 3.

This clever loop transforms a humble flicker effect into a lethal engine by leveraging the passive amplification of Swarm Intelligence and the relentless triggered ability of Quintorius Kand. By using Flicker to repeatedly reset Mystic Sanctuary, you ensure a fresh supply of instant spells right back to the top of your library to fuel Quintorius Kand's discover-style ability without ever running out of ammunition. Every single iteration deals guaranteed damage and gains life while keeping the entire chain going indefinitely.
