There's an important caveat: don't pick champions you're not good at. It's all well and good picking a counter, but if you can't play them well at all then you're still going to do poorly if the enemy's even moderately experienced. The number of times I've seen people pick Talon into Kass because "he's a counter" and then feed horribly...

(Same goes for picking "OP" champs. Long time ago when Kass was the pick or ban champ my friend was in a game where his first pick saw Kassadin was open, took him immediately and then asked "Does anyone here know how to play Kassadin?" They didn't win that one, shockingly.)
