Lots of mechanic changes coming this update. Buff/Debuff type resistance, using the same character on the same team, 4/5 & 5/5 Grid nodes, etc. The later is huge as up until this point there was little point in fully maxing out units unless they were your favorites/bragging right.
Both Halloween Iris and SS Wally are looking to give their respective types some majorly needed buffs with Poison & Fairy Zone. Of course there had to be a Poison Type Hyper Beam someday. I will never understand the popularity of the Hex Maniac, but more playable NPCs are good.
I'm surprised we're getting 3 Galar units this month, I was kind of expecting them to save Victor for the Galar Villain arc. I wonder who will end up getting Cinderace now?
Will probably have to pull for Raihan now that he's coming to the Trainer Lodge. It's been only a month and I already have 3 Lodge units unlocked. If they are only adding one a month, for many players they will probably run out of interact-able units by the end of the year.
The last of the Hoenn units are getting their grids so all that is left are units from Kanto/Unova. Only four more 5* units need their EX now that running meme Glacia has hers. Datamine also confirms that Colress now has a model, so if it wasn't already an easy prediction, it looks like the Unova Villain arc will be next month. If so I'd expect for Cheren to get their EX/Grid next month as well.
Also Happy Birthday!
