Aye, nice team you have Magic. Its pretty solid all around, but there are a few playstyles and threats that give this team trouble. The biggest playstyle that you have trouble against is stall. Even though goth is banned, stall is still a fairly solid playstyle. You have ways to put pressure on it through SD breloom, SD Mega Pinsir, and Kyurem-Black, but the problem is that you can't break stall. Everything on your team can be handled by atleast 1 mon on stall, and lando-t is going to have a hard ass time trying to get rocks up on Sab teams.
Like AM mentioned, and what I 100% recommend is running Focus Punch Breloom. Focus Punch Breloom allows you to break fatter builds, which is really nice when Kyu-B is your only wallbreaker. Having both Breloom and Kyu-b makes your match up against fatter builds a lot better, and IMO doesn't make you that much weaker to faster builds. As SD is nice, but it doesn't even help that much against faster builds.
TBH there is not much that you can change without losing something important to the team. I was thinking you could run CM Latios over Kyu-b to add a decent Zard-Y switch in, however, it makes your match up vs fast electrics more difficult. You also lose a great wallbreaker for "good" one, but latios also helps against base 100 wallbreakers, as they outspeed, resist, and kill most of them. For example: Medi, Zard-Y, Manaphy, Kyu-B, and Specs Keldeo. However, like I said before, the change to CM latios depends on what you want to be weak.
That all I have to say. Nice team :]
