What to Prioritize
Mega Aggron is the centerpiece of this event, and if you're looking to maximize your time and resources, focus on raiding it. As a Steel/Rock type, Mega Aggron can impressively tank hits with its high Defense stat, making it a solid choice for raids, but its offensive capabilities are limited. You'll want to use Fighting, Ground, and Water types to take it down quickly. Pokémon like Machamp with Counter and Dynamic Punch or Garchomp with Mud Shot and Earthquake will do the job effectively. Don't overlook the importance of bringing a solid team to take it down efficiently.
The Bonuses Worth Using
Interestingly, there are no listed bonuses for this event. That means you won't have any extra incentives like increased catch rates or bonus Stardust during raids. However, this can be a double-edged sword; you can focus solely on the battles without worrying about maximizing bonuses. Pay attention to your raid pass usage, as you won’t be getting any extra perks. Make sure your team is optimized for this raid to compensate for the lack of bonuses.
Is It Worth Your Time?
If you're a competitive player or someone who enjoys collecting Mega Pokémon, this event is worth your time. Mega Aggron has its niche in the meta, especially for PvP battles, albeit it won't dominate like other Megas. The chance to encounter its shiny variant adds an exciting element, as there are only two shiny forms available during this event. However, if you’re not invested in Mega Aggron or already have a solid Mega roster, consider spending your time on other events or activities that yield better rewards.
