Actually quick attack is more useful than you think. It seems trash too but until you battle a lot on netbattle, you'll see why every time MUST have at least one quick attacker.
Quick attack advantages
-stop 1 hp reversal/flail users
-last attack against something faster than you (most of the time against alakazam. If you sword danced but is weak and you're against alakazam, go quick attack for OHKO. Alakazam is faster than a lot of pokemon, but if you have quick attack it'll save your butt)
-stop salac berry abusers who relies on salac to sweep
Exploud is definitely UU, but in a UU team it's certainly a powerful team member ^_^
Exploud- [atk + / sp.atk -] @ leftovers/chesto
EV: Hp, atk
-return
-counter/rest
-shadowball
-extrasensory
It's another one of those Pokemon capable of anti Weezing too ^-^ High hp allows it to have a good use of counter. Return for STAB, and Shadowball is for type advantages. If counter doesn't suit you as you think its def is too low, then use chesto rest perhaps.
