First team: 6/10 for being at least better than the average wifi team. It'll get you wins most of the time, but it won't win you a tourney anytime soon.
Second team: 4/10 for my manakete bias.
My point is that ballista aren't very useful on wifi. They can be ORKO'd by most every unit, have terrible movement, and take a spot on a team that could go to a much better unit.
idk, I've just always wanted to use one of these :P
It's gonna take more than skill to beat anyone with a ballista team. I'd say you need a support team.
