“It (Spiritomb) is also based on a
Buddhist tradition performed on
New Year's Eve in Japan. A bell is rung 108 times to chase away the 108 temptations in order to achieve Nirvana.” -Bulbapedia
Spiritomb, one of the coolest Pokemon aesthetically and story-wise, but it’s just lackluster competitively. Why use this over any other Ghost or Dark type, or even over it’s Prankster-abusing Ghost/Dark cousin, Sableye? Well here’s the reason: Mega Spiritomb. With a whopping 585 BST, stellar defenses, nice attack stats, and a plethora of new moves to abuse it’s new ability, Prankster, Mega Spiritomb puts Sableye in it’s grave (Pun intended).
Flavor time! Slack Off? Why Slack Off? Well, the answer is in the quote above you! Spiritomb is based on a Buddhist tradition where a bell is rung to chase away the 108 temptations, which also resemble Spiritomb. Laziness is definitely a temptation, so naturally, Spiritomb gets Slack Off. Stealth Rock is a guilty add of mine, but to be fair, it lives in a rock. Parting Shot is a verbal threat to the opponent, a Dark move indeed, and Spiritomb just looks like the kind of guy to tell you to FUDGE OFF! As for Prankster, read this quote: “It was formed by uniting 108 spirits. It has been bound to the Odd Keystone to keep it from doing any mischief.” -HG/SS Pokedex. Need I say more? It’s a mischievous little beast isn’t it?
Finally, how will this affect the metagame? Mega Spiritomb will definitely make a splash in OU, like a Sableye on steroids. Will-o-Wisping Garchomp, Mega Mawile, Bisharp, etc., Taunting Mega Venusaur and Chansey, and even being used as a pivot with Parting Shot! For the most part, Mega Spiritomb is a status master with a bite to it (Sorry Sableye), abusing it’s nice status movepool, while having the essential attacking moves (Sucker Punch, Dark Pulse, Shadow Sneak, etc.).
