Ways to improve my Soulsilver Pokemon Team?

what i always do is teach a move of both of it's types (or just one move if it only has one type) and then teach moves that are super effective against the type of pokemon that it's weak against. if you have the tms, teach arcanine sunny day and solarbeam, solarbeam can be used instantly when its sunny and fire moves are also powered up while its sunny. you can then teach it any powerfull move you want. i too have a gengar, his moves are shadow ball, focus blast, destiny bond, and sludge bomb. as for dragonite, GET HIM A VERY STRONG FIRE MOVE. you will need it when facing ice pokemon, they deal 4x damage. replace dragon dance with dragon claw and youre good to go. if it was me i would have kept twister, you can reteach it with a guy in blackthorn city for a heart scale (i have no idea how to get one without an action replay) the best thing to do for typhlosion would to give it a variety of move types (you can also swap ideas with arcanine) this strategy eats up a bunch of tms but it really works, you would be prepared for anything.
