It's probably too late to mention this, but I think grouping kingler and raticate together is kinda misleading. Kingler should be a given on any UU team, but should be mentioned alongside kabutops instead, as those two compete for a slot. Raticate should be mentioned alongside machamp and fearow as the normal physicals, as they're the ones that compete with each other for a spot. I'd say bind is the best fourth move on tangela. It's not going to sweep with it, but it's nice for easing prediction and getting free switches. If wrap isn't legal then growth is probably is the best move. Also blastoise should probably be mentioned alongside vaporeon. It's an inferior bulky water that probably shouldn't see much use, but it does get earthquake to 2HKO buzz and counter to surprise things like kingler and raticate. I think the blueprint for a good UU team (not in order) is buzz tangela amnesia kingler normal fire/venomoth/ground/second water.
