Oh man,
Toxic Chain. IF on the rare chance it just always badly poisons the target, then it might actually be threatening. See, here's the thing about the top pokemon:

The sheer boosting factors of

,
Sword of Ruin,
Intrepid Sword, and

's overwhelming 185 attack make it the absolute strongest physical attacker in the tier. The strongest special attacker is a polar oppsite

,
Beads of Ruin,

, but it too is frail to even be a glass cannon - it's just glass
Now with that being said, Let's look at Mega Venusaur's stats

It's the best Grass-type by an unreasonably large margin, with runner-up being

in most cases. Looking at its stats, it's... not actually bulky. Or has that much attack honestly. It's just the only tool Grass-types have. Terastillization could help it, but turning into a Grass-type isn't ideal in the long run, and reverting from a Grass-type with a
Flower Veil partner has moments before disaster written all over it. Even in using

vs a

duo, a super effective - say Metronome Fire Lash from

(not STAB btw) with the boosting of

,
Intrepid Sword and an ally
Sword of Ruin, that's going to KO. Maybe even Flame Wheel would KO and it's 20 BP weaker than Fire Lash. The only thing holding it back is the fact that it can't terastallize - but Grass-Poison is known for having bulky behemoths such as

. But hey thats how the cookie crumples ig
UNFORTUNATELY, the absolute physically bulkiest mon
in the game is Mega Steelix. BUT WE CAN'T USE IT due to it being a steel type. (in all fairness tho, it would be incredibly annoying to face) Guess what the physically bulkiest thing we can use is?

rhydon:
Rhydon. Fucking. Rhydon. Not Avalugg. Not even Ting-Lu. With

armored rhino is ~5% bulkier than

. Does it matter? No. Why does it not matter? Because

has HORRENDOUS special bulk.

Ok, it's not as bad as

's which isn't saying much, but it's something. It is astonishing how much wasted potential this thing has. It's even stronger than

by a good margin. Good thing

is decent enough to use
If we look at the other side of the spectrum, we have the specially bulkiest pokemon in the game being without a doubt

But you and I both know that it doesnt even use that amazing special bulk. No. Instead, it uses its ridiculous Eternamax-Eternatus equal HP stat (albeit by 5) with

to make the best use of Imposter. It does it well yes, but if it could make use of that it would be hell.
So now that we've gone over this

duo of

+

, what if you were to use it in a Metronome Battle? You would fail miserably. Because Chansey ALSO has equally bad physical bulk. In fact, it has the lowest physical defense stat in the entire game.

5 defense with

and 250 HP means it can [sometimes] tank a Close Combat. But it's not by much. And don't even get me started on its offensive stats. (just look at them) And you might be thinking, "Oh, what about terastallization?" Well I agree it's the fact that only 1 can use it in a match. They might have the best raw bulk we got, but PLEASE don't use this duo unless you are confident enough you can win games.
The next best raw bulk duo of

/

+

as a duo isnt good either. It's the same thing, but they can use an item. But the same issue remains of only 1 using terastillization.
Now, how does everything above relate to
Toxic Chain? Well as I said in a prior post, the name of the game is minimizing randomnes factors y using Ghost-types and
Fllower Veil to make yourself immune to things. But also, the other half of this is raw damage output. The multipliers a

can get is unprecedented and the same can be said for

on the special end of it. Now
Toxic Chain miiiight be hard countered by a
Magic Guard, but what if you simply can't outlast your opponent? This is the case more often than not, and the in-between of

is moreso bulk than attack. That being said, I could see

using it to great success if it were to be used. Matter of fact, anything can use it - so we could see a tiny spike in Tera Poison and
Magic Guard/
Purifying Salt.
Thank you so much for reading this wall of text. I'll be back when the usage stats are up by
doipy hooves on July 2nd ish. And with all of that being said, goodbye.
TL;DR: If
Toxic Chain always inflicts a badly poison, we are going to have a problem. Anything can use it. Sure
Magic Guard or
Purifying Salt and the like stops it, but

is still terrifyingly powerful. We'll just have to wait and see how it plays out
