I believe that spidops deserves to be somewhere on the list(although I don't know where,probably on the low tiers.).
spidops is at this moment the single best sticky web setter.

its stats are not as bad as they look.
its bulk sometimes lets it survive survive some attacks with enough investment. and pure bug typying isn't bad defensively.
this pokemon's access to circle throw allow it to punish the enemy setup users (unless if they use they use substitute), the access to the move silk trap sometimes lets it slow down the opponents who chose to stay instead of switching.
on top of that it has access to u-turn,meaning that its low speed is a blessing in disguise.
sure it may become unviable when new sticky web setters get introduced but at this moment it deserves to be on the viability list.
there are people on youtube saying that it is actually good.
I know that some players also run first impression, I am not saying that they are wrong,but I don't think that this move is that good on spidops.
the item focus sash lets it survive a hit.
EDIT: I want to add that it is certainly better than rabsca which is pure trash but somehow made it in lowest tier.
