I must be honest; I've used Dragonair a LOT recently, it's always stayed on my team, but often it just ends up doing absolutely nothing. RestTalk is incredibly unreliable, even on something as solid as Dragonair. It boosts when it needs to attack, it attacks at +0 when it needs to boost, and it seems that Sleep Talk selects Rest half the time. It's piss weak without being at at least +2 as well. I try to use it as my Sleep absorber by switching it into Amoonguss, but unfortunately it can't touch it, as Amoonguss will just use Clear Smog to get rid of your boosts. However, it IS extraordinarily bulky on the Special side, letting it actually counter Charizard, which is very impressive. I've recently switched it out for Shelgon and have been a bit more impressed. The offensive set is basically outclassed by Fraxure and Altaria, as they hit harder or have other, more useful distinguishing traits than a nonSTAB ExtremeSpeed.
