This looks like it might be a nice counter in the current meta, but I think it needs some work. The Snowspeeder is always nice to have and Zuckuss is excellent. The meta right now is based around fragile, mobile, high-damage shooters, and Zuckuss can literally tie a Cad, Han, or Dash down long enough to get hammered, potentially taking out the heart of your opponent's build in just a few turns. However, I don't like that Luke is your only cannon option. Remember, Leia's CE only works for Rebels. As freakishly fast as that thing is, a Mousie might have trouble keeping pace. Indeed, a lack of damage is your biggest problem here. If you can snare a speeder or Yobuck, you need to lower the boom on it FAST before it gets a second chance to escape or attack. Cannon Snowspeeder can hit for 90, Zuckuss can do 20, and everyone else is either a commander or fodder and will do minimal damage. That won't cut it against a 160 HP Kybuck or 90 HP, DR-10 enemy speeder. I'm really not sure as to how to increase your damage output; maybe someone else can help you with that. My suggestion is to drop Leia for a Bothan Noble; allowing Zuckuss to take a free extra shot in case he can't snare them the first time, then upgrade the R7 to R2 w/ extended sensor and leave the last two points free to interchange between the landspeeder and snowspeeder. In short, I think that this build looks good and shows a lot of promise, but some changes will need to be made before it becomes truly beastly.
