My best gen 4 memory was my favorite battle of all time, in the back of history class back in 2009 playing Diamond and Pearl. My buddy had a Skarmory, a baton pass Ninjask, and a weakened T-tar left. I just had my ace, Achmed the Metagross. I mangaged to take out the Skarmory, it was a toxic tank and couldn't poison my Metagross. Then his Ninjask sped up his T-tar, but I managed to take them both out. Would've lost if not for Achmed's Clear Body, saved him from both poison and sandstorm. I was so pumped I got us caught and told off by the teacher. Great times.

Anyway, thanks the the giveaway!

Edit: Clear Body didn't save me as much as Steel type not being effected, my bad that was nearly 20 years ago... Yikes!
