As previously mentioned, this thing is so freaking broken. After one Tail Glow, you basically 2HKO half the tier. After two, you OHKO almost the entire tier. Need I say more? Manaphy is also bulky enough to take assaults from some Choice Scarf users and can definitely take any priority. I feel that the only true counter to this is Thundurus, but even then, he cannot switch into any attack, let alone set up Nasty Plot.
