I like the new lands. They're unfetchable, sure, but they're fantastic budget duals. And they'll remain cheap because the only people who will want them are EDH players.
Also, I need some spicy additions for my new girl here. I have a +1/+1 counters/power matters subtheme going on with stuff like Drakestown Forgotten and Ignition Team as enablers and dudes like Spikeshot Elder, Needle Specter, and Heart-Piercer Manticore as payoff cards. Mostly I'm looking for ways to make it play out a little bit faster; it's a pretty casual meta, but the faster dumb memes happen, the better.
