My Crystal party sucks and there hopeless.
Somebody tell me there 6 guys.

i used the following:

Feraligatr, Typhlosion, Meganium, Tyranitar, Arcanine, and Suicune.

metagross4, what pokemon do you have? I'll fix you up a few combinations, with some other pokemon.

And Ph4nt0m0 if I used a team with mainly steel, you'd kick my butt. You got some weak spots also to water, grass, and ground.

Just 5 pokemon that don't realitvly have an overall weakness and they are:
Pokemon #1
Starter
Pokemon #2
Scyther
Pokemon #3
Beedrill
Pokemon #4
Skarmory
Pokemon #5
Houndour
Pokemon #6
Eevee

easterndragonrider i have

genger
meganium
mantine
pidgeot
clefable
magneton

I used a gengar I raised from the sprout tower, a red gyarados, my starter, and scyther, but scyther did all the battling in the end

scyther
-wing attack
-slash
-swords dance
-false swipe/steelwing

I switched falseswipe after I duplicated him for a catcher and an attacker

I loved this guy

My party is pretty solid but it might have a couple of kinks......









The kinks are there are a couple of good types that are missing....(i.e. ice, etc.)

Dude, dont worry about ice lol just make sure your Dragonite or Kingler (pref Dragonite) knows Ice beam.

My team:

(my love )
(starter ftw )
(hehe, love nidoran's near the start )
(big bad )
(yes, i know, king + queen = bad idea )
(love this guy Flamethrower, Ice beam, Surf, Psychic, what more could you want?(apart from more spaces for more moves so you can have all 4 and more at once ))

Obviously, your starter should be in the group.
In Crystal, you get the exclusive opportunity of getting a Dratini with Extremespeed on it in the cave at the back of Blackthorn.
If you have a Pidgeot/ Fearow from the start of your journey, use that as well.
Train an Espeon/ Umbreon from the Eevee you get from Bill.
HM Hoe for the free revives =/
It really doesn't matter your team's weaknesses, because if you have at least one Pokemon above level 48, you'll do fine. At least that's how I view it.
