Well, Alakazam is not broken with Magic Guard. Zam has a lot of things going for it that makes it quite a dangerous threat, however without Magic Guard Zam was easier to revenge kill and hazards completely fucked it up. It has terrible defenses, and even resisted priority after Spikes and Stealth Rocks can KO it. If you don't remember, Zam was actually UU in DPP. Even with powerful offensive moves and speed, Zam's failure to KO certain Pokemon easily leads to it's downfall. Also, a simple prediction from the opponent can leave Alakazam paralyzed by a T-Wave, also rendering it almost useless late game. Magic Guard is just what Zam needed to bump it back to OU. Most people would agree with me in saying, Zam is far from broken in OU. Now if it were Magic Bounce, that would be a different story. Also, Stealth Rocks is NOT broken. Without Stealth Rocks, extreme offensive threats like Volcarona would be pretty close to being broken unless every scarfer could out speed it at +1 and OHKO it back, or Heatran prays that it's not carrying HP Ground. Ice types would be much more dangerous, Dragonite would also be borderline broken since it would almost always be able to take a free it with Multiscale. So... no. Stealth Rocks should not be nerfed. It's essential for balancing out the already extremely offensive meta game. God forbid we make offense even more powerful.
