While that's true, why would Entei stay in on a Gliscor that has a free switch? Entei can't OHKO it, and Gliscor has Earthquake to hit Entei. Besides that, I was talking specifically about can switch-in, aka what can counter Entei, which any gliscor lacking protect (Which isn't even listed on any of the sets in the analysis) cannot do. I was not listing what can beat it given a free switch-in, as CB Entei is generally a wallbreaker, which are all prone to being revenge killed anyway, and where a free switch-in often means it KO'd the previous pokemon. You could have said the exact same thing about Azumarill, which can revenge kill with it's CB set after rocks, but would never directly switch into Entei.Talking about CB Entei vs Poison Heal Gliscor, I want to underline the fact that if Gliscor doesn't switch-in, it can easily click Roost to stall all the 8 PP of Sacred Fire which is the strongest move Entei can use towards it and ultimately win. If Gliscor runs Protect in place of Acrobatics (I don't really know why this move is shown in the calculator), the situation is even worse for Entei.
