Type Advantages/Disadvantages

[Silver]

Everyone knows about the Spiritomb/Sableye/wonder guards, but what pokemon do you find to have very few weaknesses, but at the same time, useful enough to use in your party?

Like a kingdra or a scizor, for example; only one weakness to a single type, but also have above average base stats to back them up.

Have you found anything similar to these?

My Glaceon is ICE so its only weaknesses are Fire, Steel, and Fighting.

It has Blizzard, a power move, and Signal Beam, for Psy types

Not even level 80, it has 215 Defense, 240 Sp.Atk, and 171 Sp.Def.

And Then, my Darkrai. (Dark)
Weaknesses: Fight, (I think theres more, not sure)
Lv. 76. 223 Speed, 231 Sp.Atk,
Dark Void, Nightmare Combo, along W/Bad Dreams, Takes out Chunks of Health

My Swampert, Gallade and Electivire only have 1 weakness each, and they are all beast

Oh, Bug is strong on Dark too, though bug moves aren't that common in competitive play.

Yeah, except on forretress, scizor, heracross, Signal Beam, and Yanmega

Lol, yeah, I know

Interesting combinations:
Psychic/Grass (eg. Celebi) - 7 weaknesses (Fire, Flying, Ghost, Dark, Poison, Ice, Bug)
Psychic/Rock (eg. Lunatone/Solrock) - 7 weaknesses (Grass, Water, Ghost, Dark, Ground (if gravity is in play), Bug, Steel)

The two combinations I found with 7 weaknesses. There are none I found with more than that.
