You know a good player when you see the mana base. Good deck, nice and fast, strong aggro and good burn

Jace architect of thought is better unless you're playing mill and Hero's downfall is better than Doom blade because of all the multicolor running around

You MUST mainboard Stormbreath, the protection from white clause is really only the icing on the cake of an otherwise awesome card. And take out Master of Wave unless you add more devotion to blue. At most you will only get 1-2 devotion to blue. Also, Goblin electromancer and take out islands unless you run some more blue, like izzet charm or dissolve, or what have you. Thassa's ordeal is good for devotion. Take a look at atherling in conjunction with Purphoros... holy shit what have I done... with atherling's blink ability that's an extra 2 damage every time he reenters. Please do this I guarantee it will make people cry in your meta.

I'd say take out ash zealot since flashback isn't really a thing anymore

Lotus Petal, AEther Vial, Isochron scepter, enlightened Tutor

Is this for modern or casual?

Path to exile is infinitely better than unmake, cancel? Dissipate, sissolve, delay, and I might suggest reconsidering your sideboard. Sword of Feast and Famine, Sword of War and Peace, Sword of Light and shadow, sword of fire and ice. Kor Duelist? Steelshaper's gift, darkslick shores, mystic gate,.

I don't get it

It's the best card no one expected, it's particularly good against aggro decks, as they have small creatures. But yeah I added it just for devotion but it turned out to actually be good. Also, it stopped my friends golgari deck with scavenge.

That sounds like a completely different deck lol. This is a control deck, this involes haveing control on the battle field with, card draw, enchantments, milling, discarding, and kill spells. While whip of erebos and obzedat would make for a good deck, it doesn't have a place in here

Yeah because getting rid of a card like master of waves after it's already cast is a better option

Just like the card JaceTheMindsculptor knows his shit, thus will reult in a $100 price tag and a swift banning. I'm joking of course. Thoughtseize has, and always will be one of, if the not THE best, discard spells in magic. Besides, doomblade dies to thoughtseize

Titan's strength?

How do you kill your opponent?

If Aetherling is a finisher, run 3 since you're not really having too much card draw other than Azorius Charm and Sphinx's

I edited my comment extensively :p

Reminds me a lot of my deck

That being said, I would add Thoughtseize. Also I would take out syncopate, I used to run it but with Innistrad leaving play graveyards aren't really as a big as a deal as much as it used to be. Also, with only 2 you won't be getting much early game, which is where it really matters because it's next to useless after turn 6 or so. I would run another dissolve.

With Sigarda and Bant hexproof leaving also or becoming much less powerful, Far // Away is much less needed. Also, now with Theros out and dark betrayal, putreyfy, Obzedat has become much less powerful. I sideboard Blood Baron because it's just too good.

Omenspeaker is the new augur of bolas in my opinion and is pretty good.

With the scrylands out and you running some guild gates I would recommend taking out, just one sphinx's revelation. Great card but 4 is just too many really.

Sideboard doomblade, there are just too many multicolored creatures in standard right now and doomblade is much less overwhelming than it used to be. If you want removal I would run more detention spheres or another hero's downfall.

I'm considering running 3 ashioks, why you ask? "It's not even good, ultimate is bad". True his/her ultimate is bad. However it's wonderful against aggro. I was playing against my friend's naya's deck, I was getting a free Burning tree emissary and using that mana into a Sphinx's revelation. In short, better than anyone thought.

Also I would take out the guild gate, just so "meh".

Other than that it looks good! I love control :)

Ruby Medallion

Ordeal Of Heliod is just too good, plus it activates Heroic and you draw a card and Battlewise Valor is pretty good for what it is. I would take out Bident, it's just not good.

I would splash black now and add debt to the deathless.
