This is the team so far, if you know of a way to improve the pokemon on this team, then please tell. Also you can rate the team so far if you'd like. If this team seems unbalanced in some way, please tell me, and tell me if you know of a way to even it out.

well i only have one problem with the team (its pretty good btw)

kabutops is an okay wall, but not great, whereas it's a great sweeper with that same moveset, well minus rapid spin but thats always good to have

blastoise, on the other hand, is also only an okay sweeper but if you can find a right moveset it can be a great wall

my blastoise's attacks are aqua ring/surf/ice beam/protect

true its not as diverse as urs but it gets by pretty well

Well my blastoise is scarfed, which causes a surprise for opponents who think they can outrun the turtle titan.

And kabutops isn't really meant to wall, he really only needs to be able to live long enough to spin, and if the opponent sends out something to set up, then i'll follow thru with the same thing, then attempt a sweep.

And although your blastoise is a good tank, my team already has a tank, and a sweeping tank (Blastoise) Your set is good, but it's walled by any pokemon that is ice/water type.

Other than that thnx for the suggestions

Going by the suggestions of other people, I've decided to add a member, take away a member, and replace HP-ghost on blastoise.

Member taken away: Kabutops

Member Added: Miltank

Miltank @ Leftovers
Careful nature
Thick Fat
Tank EV's
Milk Drink
Dizzy Punch
Thunderwave
Heal Bell
{Team Cleric/Tank}

And I replaced HP-Ghost on Blastoise for Rapid Spin since I eliminated kabutops.

well, i understand miltank but you may want scrappy if dizzy punch will hit evrything

Maybe so, but I went with thick fat, so I could switch in miltank on pokemon planning on using ice beam on buzzbee, or fire attacks on pinsir and venusaur.

:\ yea but if it comes down to your Miltank and a Ghost type pokemon I think you would really want Scrappy

Scrappy still makes more sense. Miltank takes hits like a beast and has a recovery move. Thick Fat isn't nearly as useful as the ability to not be walled. =/
