Hello students! My name is Professor Geekbeak, and today, I wish to draw attention to Mega Gengar. Mega Gengar is the best Mega in the Ghost Type, so even if stat wise, it is slightly beaten out by that Necrozma – Dusk Mane, it is still a powerful addition in any raid due to the boost to ghost types. Grab your notebooks, class is in session. For those who wish to do their research independently, our raw data can be found here. And for those who wish for a simple visual guide, go ahead and take a look at the below visual guide by CaptGoldfish.

NOTE: Some visual guides will be outdated for the duration of GO FEST. They will remain mostly accurate, but lack modern counters, such as the Mega Mewtwo duo, or Eternatus. Not only that, please note that some raids will not be covered in an article for GO FEST, due to the sheer volume. Our team has decided that the best call is to only cover raids who are within the top 10 counters in their type. If you’re looking for a counter that does not have an article, feel free to use pokebattler.com

Course Schedule

This counter is one of many GO FEST raids. There are too many to put a coherent schedule here, but rest assured, pretty much every legendary, mega, and shadow under the sun will be going at some point. Look to your local GO FEST event or the Pokebattler.com raid schedule to see exactly what raids will be going.

Now, some may not know this, but Mega Gengar is not a pure Ghost Type. It is a Ghost Poison dual type, which changes up the effectiveness a bit. Note that despite its Psychic weakness, Mega Gengar is KNOWN for Shadow Ball, so be careful.

Effectiveness	Types
Double Resist (0.4x)	Normal Poison Bug
Resist (0.6x)	Grass Fairy
Neutral	Flying Rock Steel Fire Water Electric Ice Dragon
Super Effective (1.6x)	Ground Ghost Psychic Dark
Double Super Effective (2.6x)	—

Mega Gengar’s moveset includes the following charge moves:

Sometimes, the weather can be your most powerful ally. In certain weather conditions, certain Pokémon on our list excel. The most transformative cases are noted below.

Overall, Mega Gengar is a difficult raid. The strongest type that Mega Gengar is weak to, Psychic, will be turned to dust by Shadow Ball. So, caution is advised when fighting it. Of course, if you wish to do more research on your box’s best Pokémon for the job, Pokebattler.com itself can be a great help! Remember, the best counter is the one you have powered up and ready to go. I grant extra credit to those who use their best friend bonus and the weather to their advantage. Class dismissed!
