Aight so UU is kinda stale atm cuz everyone's running MegaZam, so I'm gonna take the time to learn RU meta.
So outside of Froslass/Shuckle being huge dicks in hazard setup and Shuckle + Hitmonlee combo, what else should I watch out for in UU?
Hello and welcome to RU! we have a few resources at the moment that can be used to help you teambuild and learn what works best/what to watch out for in the current metagame.
First off, the RU viability ranking and RU teambuilding threads are a good place to start, they're constantly changing and the teambuilding thread isn't really complete, but taking a look at these two threads can help you build a team to start off with and optimize your sets/evs. Those two threads can be found here and here:

On a similar note, the XY RU threatlist is another place to look, its a wip just like the teambuilding thread though. That would be here:
http://www.smogon.com/forums/threads/xy-ru-threat-list.3508446/
because all 3 of these are open threads feel free to contribute information of your own to any one of them.
If you need any more specific help later on/want to chat, the RU irc channel is always open (although it might be more active at some times than others). A mibbit link to RU irc can be found here:
