CB Aero won't OHKO Metagross, but it does put a dent in it, making the whole Trick thing useless.
Trick only works when you switch something in, and Trick the counter that someone switches in. It's not "OMG I STAY IN AND TRICK HIM :)"
Not that I'm saying you didn't know that.
Lets propose a hypothetical battle.
I send in Aero, you send in Metagross. I'm not staying in no matter what, so I switch. Problem solved! Hahaha. Aero gets saved for a rainy day. Now.
CBAero OHKOs Azelf with Crunch 100% of the time. The same goes to Gengar and Rotom.
Salamence gets OHKO'd 100% of the time as well. With SR, he still gets OHKO even with the Intimidate -1.
All Metagross needs is a little wear and tear. Aero does roughly 75% max to him with EQ.
HOWEVER, after all of that is said and done. Not many people use CBAero, most resort to Life Orb and use Stealth Rock or go the gay route and use RestTalkRoarWhirlwind.
Also, major Azelf weak. One Nasty Plot that does not get Tricked will WTFPWN your team as the Azelf can at least hit 5 Pokemon with a Neutral attack (Psychic, Flamethrower but that's 4, HP Ice).
Without the -1 from Intimdate, CB Scizor 2HKOs Salamence with Bullet Punch. That means you will have to get your DD in before Scizor switch in, but Salamence takes a big hit because then you are limited to only 3 turns - 4 max because of Life Orb recoil. Now that I see Outrage only 2HKOs, that means you need to hit it on the switch in AND the next turn. What happens if Scizor switches in on a DD, that's not good.
Flamethrower just might be a good replacement for Earthquake as it does the same thing EQ needs to do for Salamence, which is hit Steels aside from Heatran (that's what you have Swampert for).
Oh snap, I see Honchcrow weak...lmao. Not many people use that though...no worries there.
Also, team is slightly less frail now with the addition of Swampert. Now you have 'Nape weak...lol. Easily dealt with your speed though.
Yeah, I haven't been on the computer much. Facebook is usually where I am and 13 year old girls stalk me on AIM, so I'm scared to get on it. Haha.
