I'm not even going to joke why I say it was a waste to even bother looking at this team. If you were battling someone it would be like them them getting a free win. Learn more about making movesets before you evn bother posting it...
A.) Groudon has low Sp. Atk, most Water Pokemon has greater speed than that of Groudon (which mean it dies faster).
B.) Water Pokemon can learn Ice Beam, so Drought won't help you when they start pummeling you.
C.) Groudon is a physical hitter, why do you think it has such High Atk and Def? Even with Drought in effect you still lose 1/2 of your HP from a strong Surf attack. So packing it with a buch of Sp. Atk's is a waste of time.
D.) Kingdra alone could kill you whole team if you havn't noticed...
