So unfortunately I did not make it to FNM this last week. Lack of funds and the first rain in Oregon made me feel like staying home. I did however get to play test my prior revision against my good friend. He was playing a Rakdos burn deck and I have never before found it so very frustrating. My Izzet Delver deck just could not stand up to it. And I finally realized that my deck just cannot handle a fellow burn deck. I built my Delver deck to compete against the creature/token heavy decks I knew would be out there. But I never really though to build it against a fellow burn deck. Sadly, I don't know that there is much I can do to make this deck competitive against a fellow burn deck, at least not the particular one I was playing against the other night.
Anyways, I have further revised my deck. You can check out MTGDeckbuilder.net, TCGPlayer.com, or just look below.

4 Sulfur Falls
2 Essence Scatter
1 Runechanter's Pike

Deck Total 
I decided to go check out some of the UW Delver decks floating around from prior to Return to Ravnica. One of the things I noticed was that almost every deck utilized Snapcaster Mage. I have to admit something folks. I don't like Snapcaster Mage. It's not the card specifically that I don't like. I know it is a powerful card and really is an awesome tool for any blue deck. But truthfully, I hate playing blue in general. I have never felt comfortable with the mechanics. Snapcaster Mage, to me, represented the obsession with the Magic community in general to favor blue spell mechanics over other colors. Regardless, I have decided to use Snapcaster Mage in this deck finally. I actually play tested with two Snapcaster Mages and immediately saw the advantage of it. So I'll probably buy another and borrow one from a friend. You
Flames of the Firebrand went away, but honestly I think it may make a comeback in my sideboard, probably as a replacement for Electrickery. The Goblin Electromancers went away. They were a wonderful card but I could not justify them keeping space in my deck while the majority of my instants and sorceries cost so little.
My mana pool was significantly cut. Again, with so little casting cost in this deck, I could not justify having 24 mana on hand when the most expensive card was 3 mana.
One of the cards I saw a lot of in UW Delver decks was Geist of Saint Traft. I searched around and I could not really come up with an appropriate replacement for this card. The one card that I thought might stand a chance was Invisible Stalker. I'm still hesitant about this, but I'll let you know how it goes. I'm envisioning Invisible Stalkers walking over to my opponent and smacking him with a bad ass Runechanter Pike. We'll see how this actually goes.
Thought Scour is now part of the deck. I saw this played in a UW Delver deck and I realized the power of this mechanic combined with a Snapcaster. I could use this at the end of an opponent's turn to feed some instants and sorceries into the graveyard. This helps me get to the cards I need sooner and stockpiles some spells I can use with Snapcaster. The only problem is if I throw away a Bonfire doing this. But I will have to make an strategic decision when it comes to that.
So there it is. Izzet Delver 1.2. I'm looking forward to trying this out on Friday. I'll let you all know how it goes.
