There is by no means a lack of viable Trick Room settersAboma is in no way one of the worst megas. It is by far the most specialized one as it plays as a Trick Room sweeper, but the issue here is the lack of truly great TR setters rather than Aboma itself.
Hail is also extremely useful to break Focus Sashes and Sturdy, a nice bonus given that most of them are immune to Sandstorm.
Bronzong can tr, sr, and boom
Aromatisse can't be taunted
Cress had lunar dance which is invaluable on tr
Porygon 2 is not dark weak and is super strong with download
Etc.
Trick room is actually one of the strongest playstyles in OU
However, Aboma is not particularly viable on a tr team. Next to behemoths like mega mawile (which is almost a neccesity, using up the mega slot anyway), crawdaunt, exploud, heatran, etc., it is weak af, and it struggles to nab those super important 1hkos that are a neccesity on TR
Aboma hardly fares well in ru. With mons like talonflame and aegislash running amock, its job is made even more difficult in ou
