Cresselia:
Do Not Ban
Honchkrow:
Do Not Ban
Porygon-Z:
Ban
Ok, I am going to say that these two weeks really haven't changed my opinion on Cresselia, which I said
here. Basically, SubCM still hasn't been that great from my experience, as it's still easy enough to beat depending on the EV spread, and it really just hasn't proved to be outstanding, especially since even at +6, Cress can still be outstalled by a lot of defensive Pokemon bar Special Attack EVs, which have their own disadvantage bundled with them. Dual Screens aren't broken either since I feel that the extra bulk isn't enough to push it to brokenness, and the fact that it, unlike something like Uxie, lacks a move to get a Pokemon in safely bar killing itself with Lunar Dance is a distinct disadvantage. Support Cresselia has been more controversial recently, but I still don't think it's broken; stall teams don't care about Thunder Wave that much and will outstall Cresselia eventually, offensive teams can muscle through Cresselia, and balance teams, while more effected by it, can still deal with it since from what I've seen, a lot of balance teams have something like Slowking who can take a Thunder Wave without losing a whole lot, which means that losing an offensive Pokemon against Cresselia is an unnecessary risk for balance teams. At the moment, Cresselia still has not proven that it has been a broken threat for the metagame, so I see no point in banning it.
Honchkrow is relatively easy to deal with imo; The Substitute Moxie set, which is by far the most common, is easy enough to stop with pokes such as Regirock, Rhydon, and other such Pokemon. Though the Moxie set is difficult to play around with since sacking a Pokemon means it gains a lethal Attack boost, offensive teams are still able to deal with it since Pokemon such as Entei can outspeed and KO Honchkrow with their own priority, as Honchkrow doesn't have outstanding speed, and Pokemon that resist it's Dark-types priority still have a good chance at beating it. Mixkrow and HP Ground Moxiekrow are annoying, but they're not broken either since both are vulnerable to status and without the Attack boosts that Moxie grants, it becomes actually quite easy to simply play around them; not to mention that priority still works well vs them. Honestly, I might reconsider Honchkrow at a later point, but I still haven't seen anyone who can really use it to a broken extent, so I'm not going to ban it.
Porygon-Z on the other hand I feel just hits too hard with too little risk. Sets such as Nasty Plot and Agility are definitely very threatening to certain playstyles, but I think, Choice Specs Porygon-Z is really the main issue. Choice Specs Porygon-Z has very few safe switch-ins, since Specs Tri Attack still decimates most Steel / Rock types, especially if Porygon-Z has obtained a Download boost, bar something like Probopass, so only Ghost-types can really take a Specs Tri Attack. However, these are taken down without much issue by Dark Pulse; iirc, standard Cofagrigus is 2HKO by Adaptability Dark Pulse, and it takes a ton more if Porygon-Z nabs a Download boost. Of course, this still requires prediction on the Porygon-Z user's part to hit Ghost-types on the switch, but the thing is, even if the Porygon-Z user mispredicts, the resisted attack will still do plenty of damage, which means that it's hard to punish Porygon-Z for a mispredict by setting up. While you can argue that you can play around it since it can't switch moves (Slowking, for example, can take a Tri Attack or Dark Pulse and switch to something which is immune / resists it), the sheer power of Tri Attack means that most specially defensive pokes can only really take a Tri Attack once before being threatened.
