Good morning let me reply to this

if u think me just saying ur take is bad i disagree, u have not seen how unpleasant people can rly be, this is nothing I have made bad takes too & I got flamed for it too??? This doesn't count as rude, u are too soft.
So what exactly is ur point? My point was they should suspect zamazenta cos I think its a bit too good, If u just wanted to say zamazenta spdef is weaker I agree ya obv since it can't boost it, doesn't change fact its extremely fat tho, then what's the point of typing of that irrelevant things to reply me?
I never said anything about caring whether ur perennial whatever that means 1400s player or whatever ur mmr is idc, I have no problems befriending newer players. U said u win arguments by logic, yes I go by logic as well and I hard disagree with whatever ur on about, who's mocking u lol if u want to "discuss" here then be open to this sort of thing. But anyway I hard disagree, any1 that's played this game even remotely long enough can tell u lack actual game experience and r just talking cap. The easiest way I can alr see this when u said just cos zama tera steel it lose to tusk cinderace bla bla, it outspeeds all of them and can Iron def 1st before taking a hit...? It beats them still...? Lolxdd then also u r giving me a whole list of sposed counters and I can also tell u lack exp from that besides dragapult that will outspeed wisp u and physdef goldengo all these r mostly counters that can be worn down over time n it's not that hard, and yea dnite is a zama counter, totally krappa
Like I said u don't win arguments just cos u act like u have a PhD in English and my English is worse than urs wdym u win by logic ur logic is flawed lol, sometimes it's so hard to understand some of these posts on here too
Trust me, I know how unpleasant people can be on this forum, I have seen that first hand. I'm sorry for the flaming, looking back over your post and from this information, it seems like you were not trying to mock me, it's just how it came across to me, so I apologise for that.
Okay, so let's go through the checks I listed. I will not talk about dragapult and ghold, since you agreed they were good against zama.
Dragonite: Is able to take any hit besides ice fang, which in that case it doesn't beat volc. As such, you can encore it and switch in something else that resists the move. At minimum, you do 25%, if you don't have encore and they have id' once. Not the best, but with encore it's a mostly free win.
Enamorus: Again, moonblast absolutely chunks it, and if it tera's? Well, there is this thing called scouting. You switch enam in, they tera steel, and then you can get enam in safely on a bp, and do 65% to it with earth power, which is most of the time enough chip for it.
Hatterene: Nuzzle, that is just the answer. Nuzzle destroys zama as it now isn't fast, and once again, tera steel heavy slam only has a 50% chance to OHKO. 252 Atk Tera Steel Zamazenta Heavy Slam (120 BP) vs. 252 HP / 204+ Def Hatterene: 288-342 (90.5 - 107.5%) -- 50% chance to OHKO
Iron Valiant: Outspeeds and destroys it with both stabs, so whether or not it tera's before valiant comes in, it will destroy it.
Landorus-T: Ice fang does max 88%, which is not ko'ing. Even at +6, bp ain't koing. In return, earth power is doing 27% max. Not the best thing in the world, but in return it is making the rest of the team better against zama, as even if it doesn't get an attack off, it can still do something.
Primarina: Again, +6 bp doesn't even ohko. And in return, moonblast does 90% max to zama. And if it tera's? Surf is still doing 43% max so you aren't helpless against it.
Raging bolt: +6 bp does ko you, but if zama is getting to that high for free, idk, that sounds like your team is letting in zama too easily. It 2hit ko's zama with t-bolt and it even has thunderclap to deal great damage to it even if it is chipped, which is around 46%.
Volcarona: If the zama has stone edge, gg's, if not, one of the most free setup opportunities. Zama can't even reliably chip it down due to flame body procs, which makes it basically dead weight. +6 bp does destroy volc, but it at minimum does 36% damage, and if we are being realistic here, at +1 it 2hit ko's.
I've explained my reasoning for why these mons beat it, and yes, tera'ing steel does open it up more to physical hits. You can easily include one or two of these on your team, and that will help a lot in the matchup. Like, Enamorus + Volc does great against this core. You switch in enam, then switch to volc to bait out the tera steel. If they have stone edge, volc might get killed, but then you can switch into enam to get off chip and revenge kill with a fighting resist. If they don't, free qd boost for volc. Idk why your saying my logic is flawed, I have explained my reasonings why zama isn't broken.
