It wasn’t even my original ideaWhat I think:
A clause seems kinda silly. I don't like the idea of random clauses for everything and I think one smash mon is almost as dumb as 2 or 3 if it's the right mon at the right time. In general I think clauses add unnecessary complication, especially when they are not commonly accepted clauses in different meta (I'm not saying this should stop us introducing something necessary - like with the comaphaze clause - but there is certainly a higher "cost" in confusion and inaccessibility to more wacky and wonderful clauses, where something like a species clause is widely known and understood so doesn't have this problem), and I really don't think smash is something worth "saving" with a clause if it's worth acting on in the first place.
I wouldn't be opposed to a smash suspect, it's always been dumb and works on literally anything with half decent stats (throwback to winning in OMWC with double simple smash zygarde-c). However I personally feel like the Borken Moves (BMs) are more borken. BMs are extremely powerful with very minor drawbacks, two of them have good PP and even if you don't go first they're 85 bp as well as having 100 accuracy while the other BM always has 180 bp with good accuracy and the stat drops are not too limiting if you net a kill with it or if its against slow defensive mons like Melmetal. BMs are the key element in a lot of borkenline sets like darmgz, random smash sets, weather etc and are extremely limiting to the meta: they force they use of quite specific defensive mons and punish running anything but the fastest or bulkiest offensive mons and are extremely spamable even by mons such as Zac-c or KyuB which have no natural STAB advantage with them.
Well anyways, I don’t know if the 3 attacks are more of an issue, tbh, as you can literally become immune to to them, (even against Mold Breakers thanks to Weather), while Shell Smash can cause almost any attack to become OP, and causes Lunala/Dawn Wings to really skyrocket with Stored Power, while Power Trip puts Bisharp and Tyranitar on the map alongside even weaker attackers like Obstagoon which was previously obscure.
Plus, many players can just run Fur Coat on a Dragon (like Eternatus) since they are all physical moves, while Shell Smash can be Physical, Mixed, or Special.
Shell Smash makes > 85 base power attacks > VC, FR, and BB, as making any decent offensive Pokemon OP can override defenses easily.
The attacks alone don’t really help Special Attackers and can each be resisted by the Dragon-type, and fail to provide consistency due to their drawbacks, while Shell Smash... well - quite literally Smashes past typical checks.
Please, don’t @ me! ;)
