Yup for commander walkers lol

Thassa? Also maybe cut one of each temple for 4 of delta and 2 mana confluence?

?, Have you thought of splashing blue? Then new draw cards that allow you to exile cards in your yard to cast might fit in here rather well.

I agree with that thought. What are your thoughts on 1 minamo and maybe even I eye of ugin?

I would drop the tangle wire all together and just stick with the they pay more for their spells idea. Tangle wire is really the only card that hurts you so why not just go more stream lined to make them pay more. Your artifact creatures at most would cost 4 more and your smaller regular artifacts 8. That would give you 4 card slots for maybe removal or cards to just get to your fin faster. Hell a mimic vat would even be great here especially if you left a sundering Titan in, or even a cheaper early creature like etched champion. There are a lot of ways to go hell even Mishra's helix if you want to tap them out and stall.

I would think you'd rather cast mana rocks and tax cards before your draw. That being said yes it cost 1 more and one that 1 in on the board it increases our academy count. However so does bell and with the card drawn you 1 increase your count for any workers you have in play and allow yourself another play after. If you cast you mine you wait till your next turn to see any upside, and if you are taling about casting it early game you are giving your opponent the opertunity to get value before you. If you are worried about the tax on yourself you should be looking to cut some creatures in your build so that's part of the reason i don't see an argument for goin strictly off cmc. I personally would run the bell, a couple expidition maps, and a minamo,school at water's edge. Mana shouldn't be an issue if your are playing the taxing deck.

If your worried about a cmc 3 your deck has a lot more issues than a bell/mine decision lol

Temple bell gets you value first and if you don't need to draw you don't have to so they don't get the card. Personally i think its a better value with the bell. The lower cost will only be of value in the first turn or two and allowing them an extra card that early may have a draw back where as you need the cards a little later in game and might not want to wait with your draw. Def test both though!

I'd rather have a couple temple bells or something for card draw. Who cares if your opponents draw as they can't play anything anyway.

Why would you need a buffer if 1. They can't cast anything and 2. Your beqters are already way higher than anything they'd have on the board?

It's restricted btw so you can only run 1, however mana crypt would also help you jump out to a good start and then you can sac it later.

Is there a reason you don't add tolarian academy?

Sundae ring Titan seems like a stud here and where's tolarian academy?

Blank spot designated for teferi, temperal archmage!

If your going to be that fast why not just run lands that get you whatever you need right away and run blue, mana confluence, city of brass, reflecting pool gemstone cavern, gemstone mine, lotus petals... whatever would work for you.

Also Sundial of the infinite could work too

I'm just saying almost every black deck will run him no matter what and every other deck will race to steal him because let's face it edh is a game of searches.

for one person at the table yeah lol

They ban stuff more due to the fact of spirit of the format. Such as things all games warp around like prime time and gizzelbrand. So i don't see this lasting long as a commander for sure maybe even in the format all together.

So If mornsong will only come out as the combo just run 1 and go 4 worldly then you have a better chance to hit only your ob's and if your one gets discarded or exiled that's fine as your not using it for the tutor anyway.

I'd cut the fallen as i think it is more important to play tutors (Worldly Tutor) and use unshackled and i'd add white to give you more reach with removal (path to exile) and library manipulation with (aven mindcensor) in case mornsong gets out first, run 4 ghost quarters and fix lands to carry white too and you might be on to something.

clear the way could hurt you too as regular ramp might be better than letting your opponents get some advantage too.

Maybe something like this
