Alakazam

While Alakazam was widely regarded as a nonthreatening Pokemon due to its lack of bulk, Magic Guard has completely reversed this. With what is widely regarded as one of the best abilities in the game now, Alakazam can sweep without worrying about Stealth Rock, Spikes, or Toxic Spikes hampering it. Additionally, moves such as Toxic and Will-O-Wisp only aid Alakazam, as they allow it to act as a status absorber throughout a match. With a base 135 Special Attack and base 120 Speed, Alakazam can be a top-tier threat for those that lack preparation. Sadly, it is hard to find people that are unprepared for Alakazam considering the ubiquity of Genesect and Excadrill. Those that can outpace Alakazam will usually beat it, though Alakazam can definitely hold its own when given the proper support.
