Help with My Heart Gold/Soul Silver Pokemon Team?

In my opinion, I favor gyrados over tentacruel because it has a higher att, somewhat similar moves, and I think its faster than it as well. For your 6th spot, I would recommend the crobat because it is a good waste of time, but maybe you could use a snorlax (Huge HP, defense, rest, Sleep talk). To be honest I'm not a big fan of fire blast because the accuracy is too low, I like flamethrower a lot more. Also, I think that Groudon is better than typhlosion (Its slowers, but it doesnt need to charge for solar beam+it has higher att). I would reccomend giga punch or focus blast because if you cant finish off your opponent in that 1 attack, your pretty much screwed for 1 turn.
