I'm looking to build a second Modern deck, and I'm considering going with an America Control build. I've already got some of the obvious inclusions like Snapcaster Mage, Lightning Helix, Lightning Bolt, and possibly Path to Exile. What else might I need to get a deck like this off the ground, and does anyone have a decklist they might be willing to share to give me some inspiration?

well though i myself don't play this type of deck things i commonly see playing against it online are:

* Supreme Verdicts
* Electrolyze
* Sphinx's Revelation
* Celestial Colonnade
* Mana Leak.

I found an okay structure here if you'd like to reference it for a skeleton: http://tappedout.net/mtg-decks/cryptic-control-done-right/

Thanks for the link! That definitely helps. As a matter of fact, I think I have the Electrolyzes and Mana Leaks.
