I was hoping no one noticed.

Detention sphere has terrible art, while lorwyn oring has awesome art.

Rarely does it matter than ORing doesnt hit multiple permanents and eventually dsphere will probably replace contamination. However, ORing is strictly worse with much better art.

I suggest adding a very minimal number of cards to make Zur a legitimate threat, as well. Possibly Empyrial Armor alone, as it synergizes with your plan, and the searchable Necropotence. One card for an alternative, and accessible method to win is an incredible investment.

There really isn't space for that sort of effect, and Zur cannot be relied on to survive for that long.

I will not win the beatdown race due to the nature of the deck. There isn't enough hate to keep other people from winning the game, and I will lose to other creature decks.

The deck only needs Doomsday and a draw spell to go off after a certain point, so in the combo attrition game we need fewer pieces than most other decks which puts us at an advantage.

Scroll Rack?

Boseiju, Who Shelters All to protect your combo?

Edit to above: You can untap Boseiju with Candelabra, effectively making your entire combo save for LabMan uncounterable.

Boseiju coming in tapped is a huge problem, and running untappers doesn't really fix that problem.

Islands are important, and our color requirements are too high to warrant a ETB tapped land that can't produce blue.

Also the deck runs a ton of it's own counter magic making boseiju not necessary.

Scroll rack on the other hand is simply too slow. That's really all that can be said about it. The effect it brings is not efficient enough to be included in the list.

Challenge Accepted:

I need to acquire 13 Zendikar Expedition lands.

9 fetches
Watery Grave
Hallowed Fountain
UW and UB new lands

Do you fetch into basics enough to support the new duals from BFZ?

Blue fetches almost always get islands.

Combined with naturally drawing islands due to the high count of them.

I think you can do away with . Aside from Angel's Grace and using white so you can use Zur to fetch Necro, is there ant other reason why you think white is necessary? already has enough tutors to ensure you get ad nauseam by turn 3.

Also, have you ever considered using Demonic Consultation?

I second the Scroll Rack and Boseiju suggestion. The deck doesn't seem to be really fast so I doubt the said cards will be too slow for it. Besides, counterbalance will work a lot better with the rack in play.

Lastly, what role does Turnabout have in the deck?

White is a splash, the only reason I'm playing Esper is because Zur is leaps and bounds more powerful than any UB general.

Demonic Consultation is too risky, since the deck generally needs multiple types of effects to win vs single cards.

This is a turn 4 deck. You will gold fish a win by turn 4 the vast majority of the time, due to this those 2 cards are too slow. I cannot afford to have lands entered tapped since I use most of my mana every turn. In addition, boseiju only protects one spell where numerous will need to resolve in order to win.

Scroll rack on the other hand really just doesn't do much for the cost.

Turnabout is used to turn colorless mana into colored or play with high tide. High tide being one of the most powerful mana generators in the deck. Which is another reason not to run boseiju.

Why Trinket Mage over Fabricate?

Already covered. They're interchangeable give the deck's curve.

Except one of them can't tutor Helm of Awakening.

"In all reality they are interchangeable in this particular deck.

All the targets worth tutoring are 1 cmc or less. I don't generally find myself tutoring for rocks outside of the ones that net mana, and even that is rare. Everything else is 1 mana or less"Answered comment 4.

Yes, I read that, and it doesn't give an explanation as to why one would use a functionally weaker option if they really are interchangeable. The deck isn't running Snap, so the fact that Trinket Mage is a creature isn't relevant.

Having a blocker is relevant sometimes.

Honestly I shouldn't be running either, and he's on the chopping block.

No Sun Titan?

He costs 6 and doesn't advance the plan.

What would he do in this deck?

Ive play tested this deck against dozens of other commander decks, and I can honestly say that this is the most competitive edh deck on this site.

Thanks :D

Glad to hear you're enjoying the deck.

I like this deck a lot more now that i've had a second chance to look at it. I'm still puzzled about the Candelabra though. I'm guessing you're using it with High Tide? It seems like one of those cards that sometimes ends up as a dead card. Am I missing something?

It can turn colorless mana into colored mana. Skuloth has said(i might be paraphrasing) candle isn't great, but it isn't awful.

Candle is great, it just isn't necessary.
