You have Notion Thief listed as a card that beats you. Simply playing Consecrated Sphinx and then either playing a cantrip or passing turn will allow you to kill the owner of notion thief via mill in one shot.

Ever considered using Erayo, Soratami Ascendant /Erayo's Essence with this? Its pretty vile when use with Jin-Gitaxias, Core Augur since he forces your opponent to top-deck unless they have something to give them no max hand size...Erayo's Essence would counter whatever they may happen to draw unless its a land correct?

I like the deck name. It's a very competitive list, and nice job with the run-down, although I do think there are stronger ones in competitive EDH. If this deck is truly undefeated... I think you need to find more competitive opponents. No deck goes undefeated for very long in a truly competitive environment.

+1 from me, but thelastbrujah is right, so don't expect to win that easy

I think my deck could perhaps defeat this deck

But it would be fun to see.

Wait.... do you actually own this?

That sh*t cray

Also according to the French banlist which is sometimes used in high-level competitive, 1v1 EDH - Back to Basics is banned, along with Mana Vault and Mana Crypt

ChiefBell - I believe this was made for multiplayer competitive decks not 1v1.

I just pointed it out because there was talk of us doing a 1v1.

Jace, the Mind Sculptor + Rings of Brighthearth isn't an "evolution engine" because adding loyalty counters is the COST not effect. Rings does not copy the COST.

Just figured I'd point that out...

why bother with snow lands if you aren't running mana doublers like Extraplanar Lens and Gauntlet of Power ?

a bit expensive I think

I think you should consider using a different commander, put Jin-Gitaxias in your deck, and also put Proteus Staff, I had a 6 player FFA become a 5-on-1 because of that little trick. I used Thada Adel, Acquisitor as my commander.

When I read "undefeated" I automatically assume your playgroup/meta is just on the competitive side of casual and not a bunch of top tier commanders. That would explain why a Jin deck is undefeated lol

Troll in the dungeon! The here's a troll in the dungeon!....thought you'd all like to know.

I am troll in dungeon :c

how do you stop yourself from accidentally milling yourself?

I like this list. I run a slightly less competitive Jin-Gitaxias list, but I'm curious as to why you're not running Laboratory Maniac? It's low enough on the curve, and it's an alternative where you can one-shot deck yourself and just win

seconding what captaincarrion has said, Laboratory Maniac is a brilliant card as a backup.

Checkout the Win-cons in my mono-blue to see it's uses; Patron of the Mill

caged sun only helps you. definitely use caged sun.....

I second that

Scour from existence Or spine of ishnah will take care of Iona and akroma

If it's still undefeated it's being played in the wrong meta
