So if this deck is beatable why is everyone running it. I've found free-holders solo smugglers to be a challenge but far from un-beatable, just like Sith control was. If people look outside the tiny scope of DS cards they are used to using there's a lot of fun options to splash that help against these solo smuggler decks immensely. Until the meta (as a whole in the US) starts to adapt these counters people will continue to run smugglers shenanigans.
"if this deck is beatable why is everyone running it" assumes that the only dominant option would be a truly unbeatable deck. But that's not the case. Smugglers right now are head and shoulders above anything else the light side has to offer. It is beatable, but it's less beatable than anything else out there.
