Mario & Sonic Guy
Old rivalries live on!
Rock Head is pretty much useless on Golem if it can't learn Head Smash though. Sure there's Double-Edge, but Earthquake and Stone Edge deal more damage with STAB.I caught a shiny graveler in horde mode luckily, with them knowing magnitude and the shiny having rock head...
Besides, in most cases, Golem is better off having the Sturdy ability.
It did suck, knowing that you couldn't use any uber leveled legendaries in a random Wi-Fi battle. On the other hand, if ubers are allowed, you can't even do one match without running into a Mewtwo, Ho-oh, Rayquaza, or even Kyurem.and the Wi-Fi battles are a lot easier with the hacking gone but now people are abusing the no legendary restriction being lifted...
