Hmm, the only difficult thing about testing a team with Excadrill is that you're forced to play in the Ubers tier on most servers. I tried to play on the PO server because I thought that it was pretty lawless there. Last time I went to it, they allowed Blaziken, Chomp, Thundurus, and Excadrill. So, I figured they didn't adhere to our Smogon lore, however this was not the case, when I went there yesterday. I clicked "find battle" and found myself staring down a team of Kyogre, Arceus, Palkia, Mewtwo, Dialga, and Giratina. lol
So, does anyone know of any servers that allow Excadrill to be used in OU?
