I meant use it in ou.
Anyway, about the latias tbolt
manaphy uses CM, opponent switch's in latias.
manahy uses rain dance, opponent trys to ko with tbolt, u lose 45%
manaphy uses rest after latias just misses the ko with tbolt
tbolt, then you CM again
tbolt and you rest
tbolt and you CM
you can see where this is going can't you

The cycle would have stopped on the bold line, when your opponent switches to ScarfTar and force you to sleep for two turns or take a Surf (heavily, but he'll survive a +1 Surf in Sandstorm with around 30% left). NightmareZ, I'm aware you respect Phil, and so do I, but do not just go "Oh Phil think's it's Uber, so it has to be", make up your own mind from your own experiences.
Oh, and to the people who go "Manaphy can just switch out and kill you again later", that pretty much mean
he has been countered or checked. The definition of a counter is one which can switch into the designated Pokemon and force it out. Saying Manaphy can switch out of +1 Outrage means he lost that encounter. If this logic continues, we can pretty much deem every powerful Choice Bander as an Uber, because they could just switch in and kill something provided they predict correctly. Let's just use a ridiculous example, Slaking. Choice Band Slaking, if predicted correctly, can pretty much OHKO a massive proportion of the metagame. In the ideal world, he can switch in, OHKO something, switch back out, come back later, OHKO something else. At the moment, he is NU, not even OU material, because he is garbage. CB Dragonite is another great example, able to 2HKO pretty much the entire metagame provided you predict correctly, but Dragonite isn't Uber by any means.
Anyway, back to the test, I am very surprised next to no-one has mentioned Shaymin as a Manaphy check. If running Specs, it speed-ties with Timid 252 Manaphy. Seed Flare threatens to OHKO all unboosted Manaphy that hasn't got a Calm Mind in, and even if it has, it can keep Seed Flaring RainResting Manaphy until a Special Defense drop, in which it will OHKO next turn. It 2HKOs Phil's Manaphy at +2, so if Seed Flare misses, he still won't be able to set up, not to mention that Special Defense drop.
It is rather a shame that the test ended early, though. I was about to test the counter to ALL Manaphys (Ok, maybe apart from physical Manaphys, which are lol), and that would be Calm Mind Blissey!!
