Kangaskhan: Do not Ban
Reasoning: It's broken on paper, it centralizes teambuilding a lot but is often pretty underwhelming ingame, lacks power and has a plenty of good and popular checks. I need to see more before joining the ban kanga train.
Exeggutor: Ban
Reasoning: Eggy is super splashable and is way too powerful for the pu metagame. If you don't run av perrserker you just can't switch into it. its solid bulk makes it even harder to deal with. The only thing that is holding it back from being absolutely broken is its weakness to U-Turn, but that's not enough to keep it in the tier in my opinion.
Perrserker: Do not Ban
Reasoning: Perrserker's crazy good atm, but offensive sets are nowhere to be seen. Indeed, the assault vest set has largely taken the upper hand and is a glue for the more offensive teams. Admittedly its offensive presence might be like Kangaskhan's, unmanageable on paper, but I think that these offensive sets haven't been used enough, so I can't confidently consider them broken
Pincurchin: Ban
Reasoning: Electric Terrain is way too good for PU, not only that it pushed mons like Swoobat a bit over the top, but also the strategy of seed + random specially offensive mon is just unmanageable. Pincurchin isn't broken on its own, but the whole Electric Terrain strategy is, and I think banning it is better than doing some complex bans just to keep it.
Alcremie: Do not Ban
Reasoning: Alcremie is a fantastic addition to the tier that has comfortably established itself as one of the best mons in the tier. It has plenty solid offensive and defensive answers, is a great defensive win condition and has a great special bulk. It's still a bit frail on the physical side, even with defensive investment, which makes it way more manageable.
