Pokemon Fire Red - Pokemon Team Help?

i havnt played pokemon in a long time but i have spent hundreds of hours playing pokemon from the gameboy color to the game boy advance to the ds. Yes you do indeed have a strong weakness in your team, that is magneton, i would get rid of the electric type, it doesnt affect ghost pokemon, and its week against grass and fire, and water pokemon tear the electric type up. and yes i would suggest having a good flying type. and arcanine is a fire type right, im pretty sure he is, and thats good you need a fire type.
