Also Soldevi Excavations is a better Coral Atoll imo.Check the official banlist of WotC - http://magic.wizards.com/en/gameinfo/gameplay/formats/commander

I just checked the ban list on wizards gatherer of Erayo, he is only banned in Block, Extended, and Standard. He is legal in commander and the others. I would not be using that suggested land because I can't afford to be sacrficicing lands.

That is simply not true, not true whatsoever...

I am on mobile so it is very hard to put a URL here but you can either check gatherer.wizards.com for the ruling or I'll post the url from a computer in 4 hours.

If you click the link, it'll send you to the website.

Madaraximundar,
Here's the official EDH rules site (Wizards supports EDH but doesn't "own" it, so you have to go to the official source ... Gatherer is sometimes out of synch, and T/O almost always is): http://www.mtgcommander.net/rules.php

Sorry, but Erayo, Soratami Ascendant is currently quite banned.

clayperce and zsedcx22,

Can either of you think of a replacement similar to Erayo, Soratami Ascendant? That card was invaluable to this deck. Preferably another 2 card combo like Arcane Laboratory + Erayo, Soratami Ascendant .

Eliminating those two for Fabricate + Nullstone Gargoyle .

Glen Elendra Archmage is a lot better than Nullstone Gargoyle, dude. Why give your opponents the choice of which non-creature spell gets canceled? All Nullstone will do to your biggest threats will make them waste a non-creature spell to push through a more important one. Did you notice the persist on Archmage? Once she's out, she becomes very hard for your opponents to work around. There's a reason she's a pricy card.

Fabricate has so few targets that you would want to grab with it that I don't know that it's worth spending a slot for. If you had more artifact shenanigans going on, I'd say go for it. But in this deck, having a card just to grab you Nullstone Gargoyle or maybe Gilded Lotus isn't that fantastic.

Why only have two go's at cancelling when the first of every opponents one is gone? Glen Elendra Archmage is only good for two go's unless I replace more cards to keep the counters going. Whereas Nullstone Gargoyle is every turn.

Listen to the guy, Nullstone Gargoyle is garbage for 9 mana. As it also affects you, it counters your own counters if your opponents are smart enough to play around it. Glen Elendra Archmage is basically two counters for the price of one.

Also good counters you aren't running: Mana Leak, Spell Pierce, and Mystic Confluence. Forbid is also strictly superior to Cancel, and if you have the draw to support it, opponents beware. Take out Mindstatic for at least one of these; your opponents shouldn't be able to pay past a 4-cmc counterspell.

It is a bad idea to run counters with "counter unless controller pays..." because after turn 8 they will have plenty of mana to pay those easily and then it's wasted mana on me. Mindstatic is there for a timed last resort cancel. I will take out the gargoyle but not for the sacrificing cancel.

Spells like Mana Leak can be payed past in the late game, sure. Doesn't mean they aren't effective in the early game, where you can kill people's attempts at gaining an early advantage. Their use in commander is limited, so I won't be pressing you to hard about those, but at the very least Mystic Confluence easily has the versatility to be worth 1 mana more than Mindstatic which you should at least run Dismiss over anyway; if you're going to be countering for 4 cmc at least make it a good counterspell instead of a crap one.

If. If I see cards like that in the early game. I could shuffle and those cards are in the bottom 50. I never ever put a card in that isn't 100$ effective at every stage of the game. Cards like Mana Leak aren't good at later stages. I would not use Mystic Confluence as some of it isn't good at every stage.

However, I will replace Mindstatic with Dismiss.

I could point out a good few cards in your deck aren't good at every stage of the game, but that would take too long because there are too many.

Draw cards and return target creature are both good at every single stage. Counter unless they pay 9 is also rarely going to be paid. I would agree that the card would be underpowered only if the modes couldn't be duplicated, but they can. Best case scenario, you can counter or bounce and draw 2. Worst case, you don't have good targets for the bounce mode and no spells to counter and you still draw 3. In the in-between they pay past your counter, burning some mana, and you still draw two, or bounce three problem creatures. You can deal with so many threats at the same time with Mystic Confluence, and at worst you still get a pretty decent card advantage.

I could also list plenty of your decks that need a rework, but also too many.

I recognize the versatility of that card, however for a 5 cost it's not worth the abilities. 5 cost to draw a card? I can beat that cost. To return a creature? Unsummon and Vapor Snag are considerably cheaper. And the counter ability unless an opponent pays whatever is only good early or during a moment you catch them low on mana. And any half-smart player will keep mana ready to pay that at any stage past having 6 or 7 mana to spare.

So while I am grateful for your suggestion, that card is not for my deck.

Depending on your budget you could consider running Force of Will or Pact of Negation, since you can surprise people with countering spells for 0 mana. Also, you might want to consider Deadeye Navigator and Sphinx of Uthuun as even when not together can be very effective at saving your creatures and drawing you cards. In addition to those, clone effects can be very powerful e.g. Clever Impersonator, Sakashima the Impostor, and Phyrexian Metamorph (it is also to be noted that Rite of Replication and Blatant Theivery are more excellent cards to include in a mono blue deck). I would also consider not running Knowledge Exploitation a big mistake since you can easily go get your opponents' own one or even someone's Praetor's Counsel (which does recur Knowledge Exploitation). Oh yeah, and Bribery is an extremely competitive and powerful card as it both removes an opponent's win condition whilst giving you the board control (be wary of Homeward Path though).

RIP formatting, sorry if that's hard to read.

Force of Will and Pact of Negation are indeed too expensive. I'm trying to keep the cost under 300 as I plan to purchase it once complete. Sphinx of Uthuun is a card I personally own and used in a past 60 card cancel deck. I found the card way too risky did not often end in my favor. Clone effects can be powerful but i don't any creatures worth taking cards away to clone. The Rite and Exploitation cards are beautiful, but the cards are too high cost for me. Even mid game that's emptying my mana pool that's better suited for cancelling. And since I have no rogues nor will I, prowl is useless.

While taking creatures is nice, I can't see myself taking win or cancel cards out for the possibility of finding something good.

What about Elite Arcanist to get more use out of your counter spells?

Whoops, I looked over your revisions and see you already took it out.

Desertion, Remand, Stifle, and Mystic Confluence all look like good budget options if you're trying not to break the bank. Otherwise, Force of Will and Mana Drain are decent :)
