Are these good pokemon teams, u can make any suggestions or comments?

My best advice is that if you want an all-around good team; make sure that your pokemon's moves are complementary of each other. A good example of this would be: charizard- sunny day/flamethrower; gyrados-rain dance/surf/ice beam/hydro pump. etc. Always remember that sunny day and rain dance can cancel each other when used on the other. Toxic is a nasty move; 100% accuracy and the damage builds as time goes by. I also like thunder wave; 100% accuracy and if you use a high damage move like body slam, roll out, etc. you can increase the chance of recurring paralysis. You can also use hyper beam twice if you do this; if your beam knocks out your opponent and then another appears you can use it directly again without recharging. Other suggestions, just keep your pokemon's stats in mind at all times! Dual types are usually better at defense rather attack; b/c of different matching. Future sight is also a good move to use; especially if the pokemon using it is already weak because it always hits (with a few exceptions) Hope this helps.
