Its quick and does fast damage but its OHKO range is laughable. You're going to OHKO 2+110 hp pokes (given that you spread two to them already)? GL with that. I don't your middle stat. Yeah I Ko my electrode. Then I power up something else on my bench with electrode (where did you get discarding 3 energy? You're discarding 11 to ko my guy so why can't I lose 2?) and keep charging at you. How does kingdra plan on beating eeveelutions? Garchomp? Kingdra needs 1 energy on him to wreck havoc on the active for 40....then you need to toss 2 energy cards (of your 14? 16? Anything more seems too high and yet anything below 16 sounds like you'll never ever have 2 in your hand to toss). How do you beat it? Figure it out yourself; not that hard.
I'd like to invite you to MSN so we can have a nice long conversation in which I convince you of just how much of a murder deck Kingdra can be.
Don't forget that in the early mid-game, Kingdra can discard other cards as well. If you play a more setuppy version of Kingdra, such as what I do, then you'll also be discarding Pachi's, Bebes and that kind of stuff.
Now, I won't OHKO a lot. But I'll be spreading 20's around your 130HP bench, so I can 2HKO them all. The OHKO's I pull will start happening mid-game. After I do it once, there is so many energy in my deck which ends up in my hand at lightning speed, thanks to Claydol-Alakazam-Felicity.
Now, what I meant with counters is this. You can KO my Kingdra, and in the process lose 3 Energy, or lose your Electrode, whatever the case, you're losing a lot. Up comes my next Kingdra, who is ready to go for the meager price of ONE energy. In fact, once I get set up, I keep retreating my Kingdras to speed up the discarding process even more.
You needed 2 turns to get your Electrode ready. You'd have needed 3 turns for a potentional Electivire/Luxray/Whatever kill. Its a matter of Energy>Damage ratio. Same way why Ex's were so good. Not cuz of their higher HP or their higher damage, but for the Energy>Damage ratio. If an Ex killed 2 of your pokes before going down itself, it costed him 3 energy opposed to your 6. Worst case scenario for the Ex is a draw. Its what works for Kingdra as well.
Simple math comes into play. If I can keep up a rapid fire on your pokes for just 1 energy and you need to discard 3 energy just because you want to OHKO ONE of the FOUR Kingdras in my deck (Not accounting the 3 TSD's you'll find in my build).
If you wish to beat Kingdra, play your own gameplan. From what I see, Leafeon will be dangerous for the 'Dra, being able to outstall it a while with Leaf Guard + Resistance. Armaldo will be annoying too but will just prompt more Pluspowers and Bucks in the Kingdra build. Garchomp is a joke, its just too slow to keep up with Kingdra. Blissey? Don't make me laugh.
Keep that 20 snipe in mind. Its more dangerous and important as you like to think.
