it was a running joke that all special abilities worked once.
and only once.
Your DM seems to be overdoing counter-tactics against PCs (Maybe except for de-buffing. It is popular and generic enough). But I am curious, how many PCs are in your party? And is the party composed well?
One creature can't have all the abilities at once. So usually, if all the creatures you meet counters one PC's signature tactics, other PCs can deal with it.
Also, if all the enemies you encounter has the same ability, that means all of them tend to have the same weak point. So it is easy for your party to exploit that weakness. Say, if all the opponents has immune to fire, they are not immune to other abilities, and many of them are vulnerable to cold. If all the monsters are flying ones, party sorcerers can learn wingbind or your party druid can use Control Weather often. Or your party can just run into a buildings or caves. If all the opponents you meet can cast Mordenkeinen's Disjunction, they are either all mages or someone has very high UMD and using scrolls. That means, they are at not the least top class warriors. Just go into melee fast.
