Alakazam secures wins versus almost every physical attacker with the combo of Barrier, Recover, and Encore.
Marowak beats Electric types like Crunch Raikou and Shadow Ball Jolteon that threaten Alakazam. It also covers Blissey, Heracross, Steelix, and Tyranitar.
Raikou beats most opposing Alakazam with Crunch and naturally covers water types like Suicune that threaten Marowak. Rest is used to beat Toxic users, and Thunder maxes out damage.
If Thunder isn't your preference, Zap Cannon can paralyze Light Screen Alakazam, or Psych Up can be used as an additional Jolteon check.
