My first post ever on Smogon, and it's for Seaking.
Is anyone else taking an interest in Seaking using Lightningrod? This allows him only one weakness, x2 to Grass, which can easily be remedied. When you know you're about to get zapped by an Electric attack, bringing in Seaking:
Seaking @ Atk 252 / SpA 252 / HP 4
Nature: Quiet w/ Zoom Lens, Rash/Mild w/ Choice Scarf (1)
Hydro Pump / Surf / Scald
Blizzard / Ice Beam
Megahorn (2)
---- (3)
1: Something I'll be testing out will be the proper nature and item. With Quiet and Zoom Lens, Seaking gets a 96% accuracy Hydro Pump and 84% Blizzard if it's outsped, and assuming that the opponent is bringing in a Grass-type, Blizzard and Megahorn'll cover a fair amount of dual-type Grass Pokemon. Choice Scarf, however, would allow Seaking to hit quicker and possibly live a little longer.
2: Even with the proper EVs and Nature, I'm pretty sure Seaking's stats are built so that Megahorn will always do more damage than a Signal Beam, though confusion status is nice every now and then.
3: The last move would be up to personal discretion. Substitute, if applicable, would allow Seaking a bit more survivability. Flail could also help in rounding out Seaking's coverage, though HP: Fire or Fighting may be wanted in case a Steel-type shows up.
I think I might play around with this a bit longer. Maybe it'll turn out to be something useful.
