>>13936998Alakazam doesn't get any punches in RBY unless you trade from GSC, and tradebacks are usually banned in competitive play, and while he technically has no weaknesses, his defense is so shit that he gets wrecked by nearly any strong physical move anyway.
Overall, Tauros is better because he's much bulkier than Zam and literally threatens EVERYTHING in the game, while all Alakazam sets can at least be walled by Exeggutor. Not even fighting-types can stop him since all fighting-types are ass in RBY.
