Mind Flayarrrs Precon: Decklist, Value, and Verdict

The verdict on Mind Flayarrrs is that this deck is sweet. It reminds me a lot of Undead Unleashed, the Dimir precon deck from Innistrad: Midnight Hunt Commander. It’s super powerful, has an excellent commander who will absolutely reshape the casual EDH meta, and offers nearly triple the MSRP in value across a dozen or so cards. It’s everything we want to see in a Commander precon.

Captain N'ghathrod leads the Mind Flayarrrs. I’ve been super excited to write about this ever since I saw the commander spoiled. The Captain gives all your horror creatures menace and mills opponents equal to the damage they take from horrors in combat.

The catch is that you get to reanimate an artifact or creature put into an opponent’s graveyard from their library that turn at the beginning of your end step. This is insane, even for Dimir. Most Dimir cards that steal permanents or spells do so in a 2-step process, where you usually have to pay a cost or activate another ability to get the card you milled or took from their hand. The fact that N’ghathrod just gets it for you, regardless of how expensive it is, is beyond my wildest dreams.

And you won’t just need to rely on Captain N'ghathrod. The deck is full of some of the most powerful Dimir horror creatures, including big names like Grazilaxx, Illithid Scholar, Overcharged Amalgam, and even Hullbreaker Horror. In fact, every single creature is a horror, which means this deck can be amplified through tribal artifacts much easier in the future.
