Hey everyone! As someone who HATES Cress and wants to see it gone, I've been sifting through our options, both in NU and below, looking for answers to this demon, and since I'm allllll over the NU chatroom, I can tell that the average player has the same problems. So, I've decided to put together a guide I've come up with on how to beat Cress and some cool options (and some weird ones ofc) for those who hate spamming Escav+my mindset and gameplan going into teambuilding and a battle.
Overview
A lot of ladder players try to beat Cress head on in a 1v1 or expect their offensive breakers to deal with it, but as we know, this doesn't always work. It's great speed tier and bulk let it demolish fatter teams or easily beat/stall out certain breakers, such as our fighters, Polter Golurk depending on the set, or even Ttrum. What's important to recognize when building is that beating Cress is a TEAM effort, even with a dedicated answer hard wall in Escavalier. Going into a battle with a laid out plan beforehand is a great way to do it.
Gameplan
When building, Cress should be public enemy number 1, and once you figure out how to beat it, you'll have a wayyy easier time in game and in building. The main thing to remember is that every team should have a minimum of
2 checks to Cress, whether that means a hard wall and a soft check, two hard walls, 3 soft checks that support the team and let you abuse Cress etc. Having multiple different outs against Cress is KEY to beating it. Now, here's some of my favorites.
Hardest Wall
I know we're all sick and tired of hearing about this guy, but if you really never want to lose to Cress, no matter the set, you pack an...

- With a fantastic typing for beating down Cress and access to either CB or SD sets, Escavalier will literally never ever lose to Cresselia. The demon, even at +6, will never be able to kill you before you kill it, even if you run into the rare, but potent, Trick Scarf set. Remember though, if your team loses to Cress the second Escav goes down, you're going to be in deep trouble.
Offensive Mons/Types
Now, as someone who loves running more offensive teams, I've been trying to find a clear, definitive way to beat down Cress, and tbh, there isn't one. Don't give up hope though there's a LOT of ways still to beat it.
- With the banning of Bewear and Goro, it's now the meta of the Ghost's, whether that's

,

,

,

, or even random

, more offensive teams who want to break Cress should look no further than these guys. All are capable of offensively beating down Cress, but remember, if you rely on Poltergeist, you better watch out for those Kee variants. Running moves like Shadow Claw, Shadow Punch, or Spirit Shackle are all ways to circumvent this.
- Besides dealing super effective damage to Cress, Bug types, specifically special bugs, can use Bug Buzz to get behind that Sub and beat it with ease. Almost every single one in the game can do this, from

ofc to Specs

,

, or another FANTASTIC hard wall in

. Oh, and don't forget two other Bugs that can beat it,

and

. Both make sure Cress either can't or has a hard time sweeping your squad. The special Bugs can be a little inconsistent at times if you let them CM up, but if the Cress had set up and you had an answer in the back you didn't bring out, that's on you. A super weird, but cool, way to deal with Cress.
- I know what you're thinking. Sure they resist Moonblast, but how do they actually beat Cress without the super effective damage? Good question, but here's the answer. Let's start with our best Fire type,

. Salazzle has the unique ability of turning normal CM Moonblast Cress into setup fodder like nothing else. You take less than 0 from a Moonblast while you NP up and KO them. Psychic STAB is scary, but if your team can beat both variants, you should be fine (PACK 2 CHECKS).

on paper also looks like setup fodder, but I've started to run a lot more Flare Blitz with attack investment when I run it, making sure to outspeed Cress, break the Sub, and Toxic it. It's a soft check, but solid.

is my favorite sleeper pick. Just like Escav, it'll beat every single Cress variant, even Kee! By teching your Fires like this, you can beat Cress down pretty well.
- Yes, Spdef Taunt/Taunt SD

will usually beat Cress, but other Dark types have merit, too, especially when paired with a Moonblast Cress answer. Mono Psychic STAB can't sweep ever if you have a Dark in the way, such as

or

. I want to make it very clear that outside Drapion, Dark types for Cress are probably the most inconsistent by far, but when paired with a Fairy move Cress answer, it's really underrated.

- I know you're wondering how your own Cress can help you beat another Cress, but if you Calm Mind up together, your Psyshock will beat his, especially if you're faster. It's not a guaranteed check and you have to be careful with PP, but it's a semi reliable check you can throw on a team.
More Defensive Options
Curse
- As many probably know, Curse

is a solid answer to Cresselia (REMEMBER NORMAL COPPER LOSES 1v1), but it isn't the only Curse Steel. My boy

is another solid Curse Steel that adds other utility Copper doesn't while largely serving the same role if you try it.
Haze - Haze will usually stop a quick Cress sweep, especially for more passive and stallier teams, with mons such as

,

, and even

proving to have put in work. Just remember, Haze is merely a CHECK and none of these mons can ever kill Cress, so unless you want to PP stall for 50 turns, bring an offensive answer of sorts.
Other Offensive/Defensive Options Outside a Guaranteed Check aka How to Abuse Cress
All of these aforementioned mons are really solid, but obviously, to abuse Cress, you're going to need more than just them. When looking at Cress, it's greatest weakness lies in its passivity until it sets up, and for more offensive teams (and defensive ones too) you should be abusing this aspect of Cress through your team. The best way to do this, although semi hard to fit, is through the use of
Taunt and
Encore. What people get wrong about using these two moves, including me at first, is that a lot of people think that throwing these two moves onto a team beats Cress, but it's important to recognize that they DON'T. You should be utilizing those two moves to support your Cress answers, bringing them in safely to set up on Cress or force it out. For example, a Taunted Cress becomes Lazzle setup bait or Curse Copper fodder etc. Use those two moves to your advantage. You will have to warp certain sets and builds for it, but until Cress is gone, if you want to do run a more offensive team not named Screens HO, Encore/Taunt will be necessary imo. Taunt also has use outside of Cress so abuse it!
Toxic and Trick are more good answers to Cress, but remember, you have to be faster or it will just Sub up and block your move. Now if it's Rest Cress, Toxic isn't a great answer, but you now have 3 turns to take advantage of a sleeping Cress, so I'll preach it once again. You NEED more than one answer.
Heal Bell/Wish Support - If you're going to rely on a harder wall, such as Escav or Drapion, imo you need to make sure you can keep them healthy on balance type teams. Without the ability to keep these checks healthy, a lot of them get easily chipped throughout a match, whether by random attacks, Spikes, burns, whatever. Keep this in mind when making a defensive core.
Conclusion
Ban Cress please. But until then, I think people should start taking a closer look at some of the techs and mons I outline here, and there's definitely some I missed, when teambuilding. The biggest problem I see on ladder is people relying on shaky or only one check to Cress thinking that that will solve all of it's problems. Start trying to build around 2 ways out v Cress, even if it's a very soft check like Psyshock Cress paired with the hardest wall in Escav. Your life will still be miserable teambuilding because of Cress, but now you won't lose to it. So, for the last time, PACK 2 CHECKS AT LEAST. But even if you decide not to have 2 checks for some reason, the most important thing to remember is to have a gameplan. If you know you need to keep Escav healthy, never sack it. If you need to bait in Cress and Taunt then go to Lazzle to beat it, make sure you know how to do it. Being prepared is key to beating Cress. Be conscious about it in the builder
I hope everyone likes my post here. This was all the things I've seen, used, and lost to on the ladder in games with Cress, and after spamming it a lot, I thought I would try and help the community out in beating it down. If there's something I missed or you think I'm violently wrong about, reply and tell me why! Thanks and hf watching Cress die till we ban it :D
P.S - I threw together a small concise box of some of the mons I mentioned here. It's not every answer and I left out the Taunt/Encore options, besides Sableye, and the Dark's, but it's still a great list to consult.

EDIT: YSB in the chatroom told me that my point here wasn't clear whether I'm team ban Cress or keep it because it's playaroundable, so I want to clear it up. BAN IT. If there's one thing I've learnt prepping for this thread and playing is that this mon is 1) SUPER restrictive. That's why I decided to make a post helping people see a clear out or gameplan against Cress that isn't Escav and 2) inconsistent and unreliable at times. A lot of the gameplay I've laid out here can be beat by certain sets, whether Rest, Trick, Psyshock, etc. Cress will constantly have a way to cripple or beat some of it's answers. At the same time, I wanted to clear up some common misconceptions about certain counterplay, such as Taunt or Haze, when it comes to Cress. They do not work, especially not as a standalone move/mon/whatever tech they have. Please ban Cress.
