I'd like to report "thedmanrulz" for using an illegally hacked pokemon.
During our OU battle he used a specially defensive zapdos set (he has stated this himself). He said his zapdos had the stats of HP 377, A 189, D 201, SA 282, SD 286, Sp 237 - calm nature. YET, his Zapdos ohko'd my physical sweeper Mamoswine. So as you can see his zapdos has 0 EVs in special attack.
After calcing this, I've figured out the maximum damage a specially defensive zapdos with 0 special attack EVs to deal on Mamoswine is 73.1% - 86.4%.
i was well above the 73.1% - 86.4% range, yet my mamoswine was still ohko'd. This could only be a result of an illegally hacked zapdos, with max stats. The stats he gave me were probably just taken from a legit zapdos.
