Laddered with stall, team was pretty solid. Lost one game vs the
Swastik sample's Magearna, one to double Regen + breaker, and two to timeout ㋛
Gonna vote to ban both. I have the same thoughts as what other posters have said about Sheer Force. Magearna is also really busted, I'll post about that in the main thread.
I'm surprised more people aren't pro-ban on Regen. Coming from a Stall perspective might make me view the ability a little bit differently. I think Regen users being able to come in on any passive mon and slow pivot out is insane. Regen pivots can't be worn down by status, they don't care about item loss, and their recovery has infinite PP. I think the idea that Regenerator helps Stall more than it helps Bulky Offense is not very well-informed; type immunity abilities like Flash Fire/Volt Absorb/Levitate, as well as utility abilities like Intimidate, are much more useful for Stall. In an unbalanced meta like this, mons are so difficult to wall that Regenerator is a subpar defensive ability versus HO, but in my opinion it is the most problematic ability in the game in non-offense matchups.
Other things I think are broken are big Zygarde (as a body) and Rillaboom (as an inheritor).
