Iactually love this team, I dont really see many flaws to it, maybe just a good rain stall can be alittle problematic butwith the great set on ninetails I dont see much of a problem there.
Great time you have here and congratulations for your peak!!
Actually...I've ko'ed every politoed I used Solarbeam on...with rain up...
Solarbeam (in sunlight)
vs 0/0 Politoed: 59.8% - 70.4%
vs 0/0 Tyranitar: 56.3% - 66.3%
Solarbeam (in rain / sand)
vs 0/0 Politoed: 29.9% - 35.5%
vs 0/0 Tyranitar: 19.4% - 22.9%
Unless Pokemon Online has a glitch that doesn't include the damage halving mechanic. Ninetales is very weak. Might as well just run Energy Ball to hit both Pokemon 33% harder while letting you use an actually useful item.
I have used sunny day Ninetales and have OHKO'd many Politoeds in the rain. It might be a glitch. But even in Sun I have OHKO'd.... So I don't know.
