Misty's Gyarados has a really great attack that
does 70 damage. Its problems are obvious though: Misty's Magikarp is not good
and his pokemon power may be lethal...
But there is a way to stop these things... Brock's
Ninetales
If shapeshifted into Misty's Gyarados his power
will be ignored. If Brock's Protection is used removals will not manage to hurt
you hehe. Plus Brock's pokemon are easy to get using Brock's training
method.
So Misty's Gyarados and Brock's Ninetales will
really destroy everything. Beware of status effects and muks though as they will
prevent shapeshift. So some additional pokemon should be used together with this
combo just in case.
