I think you need to work on your lands, but I like the deck!
I think shock lands is actually two words :p
The only thing I would try to fit in here, is some pikes. Just for the extra finishing power they could potentially provide.
A delver + a pike, can win a game. (can and has)
I will probably play test this today. My build would remove one Electromancer (imho really don't need 4)
And one izzet charm, as they're the weakest of the current spell board.
To add two pikes.
Hey, you're playing a fast version of my deck :p
In my experience, Feeling of Dread is absolutely devastating with Geist of Saint Traft . Since you're running Guttersnipe as well, it could be absolutely hilarious. Swinging for an unblocked 6 and pinging the opponent for 2, plus tapping their biggest swingers and pinging for two more next turn sounds good.
Love the deck, not much more to it. Mana curve is amazing btw.
Pillar of Flame ? really good against zombies. like the deck +1
check out mine. deck:niv-miracle-strokeofgenius
Thanks for the comments guys. Feeling of Dread , Guttersnipe , Pillar of Flame and card:Runechanter's Pike are good ideas. I would actually need to playtest the deckl to see how or where I might fit those in. Probably gonna change up the sideboard a bit.
heartspain88 is most likely right about those Goblin Electromancer 's. I haven't had the chance for a playtest but if I get to run it I will.
If you'd like to judge my budget u/w RtR deck check it out Street Justice
