Swampert tested okay but still didn't last long. Some of my other Pokemon have slowly declined as well.
So I've opted for same major changes gettin rid of Slaking, Electivire, and Milotic.
Gyarados
Item: Lum Berry
Ability: Intimidate
Moves:
Waterfall
Ice Fang
Stone Edge
Dragon Dance
Overall, I found Gyarados to be better than Swampert. It survives just a bit longer than Swampert but it makes a bit of difference.
Ninetales
Item: Grass Gem
Ability: Drought
Moves:
Heat Wave
SolarBeam
Roar
Grudge
My precious Ninetales. It's kind of a place holder right now, but it's proven useful (although VERY situational).
Sceptile
Item: Big Root
Ability: Overgrow
Moves:
Giga Drain
Drain Punch
ThunderPunch
Substitute
This guy is still in trial period. It won a match against Alder and Wallace, so that's something.
Speaking of; Wallace is another "wall" to climb over. He uses the same Pokemon every time and beats me almost every time.
He uses Milotic, Starmie, and Sharpedo. This has only changed once.
