WHY ARE WE FORMATTING ALL OUR POSTS LIKE THIS 
Anyway, here's some scattered thoughts on some stuff, as well as my 50 cents on futher unbans and the precedent we're setting with Zamazenta-Hero.

Zama is
really awesome. I was pretty vocally against freeing it at first, but the more games I spectate or play with it, the better it seems to fit in. This thing just fits so perfectly onto offense without feeling like it's forcing a hand in the builder. Best set IMO is SoR/Tough Claws IDBP, with CB SoR and Fluffy setup close behind. Really, really hope this stays, it makes offense feel refreshing to play in a way it usually doesn't, while also slotting excellently onto many good HO, BO and even balance teams. If I bother to get reqs, I'm 100% voting unban, and I definitely see myself putting it quite high on the eventual VR update. I
do see a potential argument for unbanning it, particularly the exploitable nature of Fluffy birds, but I don't find that to be too much of a problem with clever building and good play. Amazing addition to the tier

I think I need to stop saying not to free things, because Iron Hands has also settled into the tier so very nicely. This guy does everything, from sweeping to being a fat unbreakable wall to wallbreaking to potentially multiple of these roles at once, but it's almost never felt overbearing. Physdef Regen is a set unlike anything else, it just does
so much, to the point of making something like Regen Kommo-o basically obsolete. Surge Surfer is bordering on a gimmick set but I'm all about that, pairing this with something like Latios is not only incredibly fun to play but, personally, I find it quite fun to play against as well. Incredibly good mon, very happy to have it here.

I've never really wanted this to be banned, I rarely found it overbearing in the builder or in play, but the longer this is in the tier, the more borderline unhealthy it becomes. The main culprit, of course, is Icicle Crash flinches being incredibly oppressive and completely thwarting common counterplay with some luck. Obviously, Pokemon is a luck management game, so you could argue that this is completely fine and I'd be willing to hear you out, but personally, I find it incredibly unhealthy when a Pokemon like Chien-Pao can completely circumvent most answers by... getting a 30% chance. This is in part due to Zamazenta-H making Fluffy Corviknight and Skarmory, who are more susceptible to Icicle Crash cheese more common, but this has been an issue with Chien-Pao for a long while. I'd like to see this banned, not because it's too powerful or too fast, but because it's unhealthy for something like this to just... have odds uncomfortably close to a coinflip to beat the most common checks.

Freeing box legendaries just because Zamazenta-H has proven not to be broken should not be our first priority right now. I do believe Lugia would be fine, maybe even below average, but I'd much rather see action taken on Chien-Pao first. Lugia itself would be fine. I'm not itching to bring a fat 106/130/154 bulk Flying-type into the tier, but I have little reason to assume it'd be broken. Glalie's post outlines my thoughts on Lugia pretty well, though I do think Calm Mind would be a perfectly valid and threatening set due to Lugia's sheer bulk and coverage. Honestly, the versatility Lugia could theoretically provide is pretty crazy, that movepool is surprisingly deep with some potentially really fun stuff such as Dragon Tail/Whirlwind, TrickScarf, Dual Screens, and even gimmicky stuff such as Imprison and Psych Up. This is worth a suspect test eventually, but I'm not clamoring for it.

This is fine when it isn't working together with Keldeo. In fact, I'd argue Iron Bundle would not only fit in, but it wouldn't even be
that good. Sure, if you count the walls, it looks pretty broken, but there's more to a breaker than just the walls. Iron Bundle is extremely predictable, extremely hard to get onto the field, and.. it isn't even that strong. It's STAB moves are either unreliable or low BP, it has no way of boosting its damage output outside of Primordial Sea or some other boosting ability, and it just falters in the face of repeated pressure or Water-resists. Choice Specs is the best set, and it's completely walled by most Desolate Land users and soft checked by basically any Water resist, everything from Scarf Latios to RegenVest Primarina can take advantage of Hydro Pump, while Freeze Dry is an incredibly underwhelming move and Ice Beam is walled by common defensive pieces from Gholdengo to Empoleon. Iron Bundle deserves another chance down the road, but much like Lugia, it's important to note that freeing Iron Bundle is far from a priority right now. Instead of adding more watchlist-worthy stuff, our priority should be fixing the metagame we have right now.
I fear with the successful Zamazenta-H suspect, the next few months are going to be met with more and more calls to unban stuff-- from the justifiable such as Ice Scales and Noivern to the questionable such as Sneasler and Magearna, and everything in between, but I think this is the incorrect approach to tiering. Testing stuff down is one thing,
but the future path of the metagame should not be defined by how much we can get away with unbanning. Rather, the goal should be to make the most competitive metagame we have with what is already at our disposal. Testing banlist Pokemon should primarily happen under two circumstances. One is where the ban is dated back to a version of the metagame that no longer exists, and the Pokemon deserves its due process in the current metagame; think Zamazenta or perhaps Noivern, which were both banned because they were broken in a metagame that functionally doesn't exist anymore. The other scenario is if we think we
need (or at least that the tier would be better with) something that's currently on the banlist. This is where the Ice Scales discussion falls, but that's not a discussion I intend to re-open in this post. Either way, we could absolutely get away with unbanning things that fall into neither of those categories, such as Lugia and Giratina, but they should
not be our priority.
tl;dr, ban Chien-Pao, fighting types are awesome, unbanning stuff is cool but we shouldn't build the future of the metagame around testing additional stuff in.
