I've got a bit of a heads-up (actually, a couple) for those of you contributing to this event. First of all, in case anyone hasn't figured it out already, Pikachu has more than one moveset. There's one that uses Special attacks, and one that uses Physical attacks. Also, these Pikachu are holding Light Balls. At first, I wasn't attempting to catch any that weren't shiny. However, something seemed off regarding the damage they were doing (for example; Play Rough did enough damage to 2HKO the NPC Jolteon, which absolutely shouldn't happen otherwise). I suspected one of three things: they're EV trained, they're holding Light Balls, or they're above Level 60. So, I decided to catch one to check for myself, and sure enough, that middle point was correct... I joined Generation 8 late, so I wouldn't know for sure, but there's a chance that this is the 1st Max Raid Pokemon to be holding an item.
Also, in response to the above post, this event goes from February 26-28.
