Hello students! My name is Professor Geekbeak, and today, I wish to draw attention to Mega Aggron. While not particularly spectacular, Mega Aggron is still a mega, so there is definitely good reason to have one if Steel is a type that you need a mega for. 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.

Course Schedule

This raid will take place from July 29th to August 4th. It is preceded by Solgaleo and Mega Salamence, coincides with Kyurem, and will be followed by Mega Blaziken, Azelf, Mesprit, and Uxie.

Steel is a particularly defensive type, only having a few weaknesses. Take heed of the abundance of rock moves, and the electric move in the charge move pool, in case one of your raiders is hit hard by it.

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

Mega Aggron’s moveset includes the following charge moves:

• Stone Edge
• Rock Tomb
• Thunder
• Heavy Slam
• Return
• Meteor Beam

The Dean’s List consists of the top 5 counters to Mega Aggron. As always, the Valedictorian, Salutatorian, and the Third Ranked will have their best moveset alternatives in a table with their rankings and a table detailing their defensive prowess against the charge moves listed above.

Overall, Mega Aggron is a pretty simple raid. Since Mega Aggron is a monotype, it makes countering it easy. However, most of the charge moves it has are not becoming of its steel type, so be careful of what you’re bringing in, in case it could become an issue. 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!
