Wanted to make a post giving my very initial impressions on venomicon. The mons have only been out for a couple of days so take everything I say with a grain of salt, literally nothing is set in stone for them at this point.

This mon is absolutely ridiculous on paper (lol), and while in practice I think you can sort of suffocate it throughout a game to where it won't be too oppressive (especially if it's knocked), it still has a lot of potential to autowin some matchups if you don't have a hard answer. In my experience, the prologue forme excels at repeatedly forcing positive trades. There is virtually nothing in the tier that can OHKO it––your viable options boil down to specs lele, specs zone, zolt under hail, or NMI/Specs Kyurem (probably getting banned)––which ultimately means that at +2 SpA you can eat almost any hit and often OHKO back with Hurricane or EP. Things like Tapu Koko, Zeraora, and Weavile fail to become reliable answers when book is at full health, because they will just deal 80%, die to EP/Cane, and then book roosts up on your lando 10 turns later. This is also largely why I don't think mystical fire is all that good; you lose your ability to cheese past electric-type answers, plus you just get shit on by heatran which is very sad. Defensive "answers" to this mon like Corv are quite bad, too, as you can freely NP on them for all eternity. TLDR, book is good.
Building with this mon was strange at first, but I've found that all it really means is you can't rely on Corv as your bulky steel/defogger or Pex as your bulky water. You can sort of get away with Corv + book because there are worse things to exist than stacking flying-types, but realistically you're also running lando 80% of the time, and running two additional bulky flying-types that overlap defensively with each other in checking fairies + grounds just feels suboptimal. Pex is also not great for similar reasons; two bulky poisons is certainly doable, but still awkward on the majority of structures. Other steel-types like Ferrothorn, Melm, Magnezone, and Heatran are exceptional partners instead, with double steel cores being particularly effective. Tapu Fini has personally been the easiest bulky water to use alongside venom, but either of the slowtwins are also solid (notably colbur bro), as well as argh if you can fit a durable rshifu/lele check elsewhere. Zone is an especially good partner for trapping steel-types that annoy it, but frankly you can work around these steels regardless––venom is a very self sufficient wincon. Offensive partners like Tapu Koko are very reliable for getting book in vs ground-types so it can roost up, Dragapult can do the same vs fairies/sometimes lando, and Weavile is nice because it gives you a soft pult check, which has otherwise been sorta weird to fit in my experience.

God this one is so fun lol. +2 TL Brave Bird is a damn menace. I don't think there's a ton to say about this that we didn't already expect; there are essentially 0 good defensive answers at +2, and if you play this mon correctly, you are in good standing to claim like 3 kills per game. That said, recoil is huge, as are rocks. I have not found venome/ebook/plane/epipen (but fr what are we calling this mon) to be particularly overwhleming in practice, despite its incredibly high peaks. Teams with a physically bulky regenerator like Pex/Bro, double steel cores (especially those with ferro), and a capable rkiller like Weav/Koko are all decently well-equipped to handle this mon. Not all three are necessary, but you should probably have two out of the three. I have also seen a lot of discussion around this thing's potential sets; things like STABs+Uturn+roost, sub+SD, and sets with rocks have all been discussed, and I don't know if we will have the "optimal" set for a while. Speaking personally though, I am very high on SD + 2 Attacks and think rocks sets are quite bad. Gunk is great for dealing with pex/lando without taking recoil, but Knock is just as good for removing tran/ferro/pex/slowbro's items early game, ultimately paying off a ton in the long run. Both have pros and cons, I don't think one is necessarily better than the other atm, but I'll say I personally favor Knock slightly right now.
Building with this has also been weird, arguably more so than base forme book. It's not quite fast enough for you to use as your sole speed control, you ideally want double removal support, and it has the same building-redundancy problem that the base forme does (though to a slightly lesser degree). Electric-types, especially Tapu Koko and Zone, are superb partners for this mon; Koko solves the speed control issue and can pivot you in on ground-types, whereas Zone's ability to delete steel-types is ridiculously useful. As for double removal, this isn't strictly necessary but is definitely nice. Defog Lando+Fog Astro/Fini/Washtom has pretty good synergy, but again, double removal isn't a "must." The type-overlap making Pokemon like Corviknight redundant is annoying, but you can get away with it better than with regular book because they aren't overlapping as much in their actual role of checking stuff defensively, merely in their type synergy. On the other hand, though, ebook can offer some cool stuff to a team; for example, using only lando or torn as your ground-type answer isn't great because they will usually get knocked/toxiced at some point, but ebook+lando is fairly competent against opposing grounds. A similar thing exists where this mon can soft-check fairies and grasses to take pressure off of its partners on bulky offense builds.

Closing thoughts:
I don't want to give a preliminary viability ranking or say whether I think they will end up nerfed or not, because it has legit been three days. However, I feel confident saying I'm really pleased with how these mons turned out, and that both are very strong in their own right. Stamina forme's probably a little better, but not by much. I've been building a decent amount with these two, and with the playtest coming up I don't want anyone to go teamless, so I'm dumping some stuff. Few builds are incomplete but I cba to finish them and maybe they will inspire someone. Enjoy:
