Kangaskhan Ban. Pretty much only reliable switch in in long terms is Avalugg. Runerigus comes in couple times, but has no access to reliable recovery and gets chipped. Kangas 4th slot offers a lot of variation to hit against this problematic ghost type eg. toxic, crunch, PuP into crunch etc.
Exeggutor Ban. Breaks through anything pretty much with specs set. Surely we have ferroseed and two unmons called vullaby+zweilous for it, but thats simply not enough. Offensively its checked well enough, but defensive conterplay is extremely limited.
Perrserker Ban. The more I have been using Perrserker the more Im convinced this thing is extremely good balance/stall breaker and with its given abilities it breaks through all its checks. Band set is almost impossible to switch and iron head is pretty braindead click. Pretty similar to Exeggutor, offensive counter plays are there, but defensively its almost an impossible task
Pincurchin Ban. Electric surge is stupid as bricks. Gives unlimited amount of threats to the tier which we can not cover in one team. No matter how hard we try. Defensively Pincurchin offers a lot as well with its double spikes, memento, reliably recovery. Alone Pincurchin isnt that bad, but paired to e-surge its easily the most broken thing in the tier.
Alcremie Ban. Unkillable mon with its acidarmor+cm+ dazzling/storedpower sets. Aroma veil backing it up is ridiculous good and prevents Alcremie getting taunted and nothing prevents its set up. Access to good coverage lets it hit hard enough against steels and poisons.
