Alakazam

Mega Alakazam is one of the best special attackers in the tier thanks to its outstanding Speed stat that only leaves it outsped by Choice Scarf users. Additionally, it can take advantage of common Pokemon like Arghonaut, Heatran, and Mega Latios thanks to its typing, access to Recover, and ability; Trace allows Mega Alakazam to copy Heatran's Flash Fire and Mega Latios's Levitate, meaning that it can effectively wall Heatran lacking Corkscrew Crash and Mega Latios lacking Draco Meteor. Furthermore, Trace is an extremely useful tool against rain teams and also allows Mega Alakazam to copy a few other interesting abilities like Regenerator, Protean, and Soul-Heart. However, Mega Alakazam is extremely frail, leaving it susceptible to common Choice Scarf users like Kartana and Greninja.
