I'm not much of a giant-robot guy, so this wasn't really on my radar, but the gamespot video's description has me more intrigued. It sounds like the loop will be similar to what I normally do in CCG where after a loss I might consider what went wrong and then rebuild my deck to address it. Here it seems there isn't a "good" build for your core as much as there's a good one for a particular situation, and after a loss you'll need to retool your build to fit.
