Hey sup. Just a few suggestions.
Body head, something like so and so throws a ferious left hook to the body, then follows it up with a left hook to the temple.
Idk man not lined like that but you probably get my drift.
Counter shots to I know you probably already have some but you the ones you see in mma like the eric silva vs stun gun they both threw the over hand at each other but stun gun timed it better.
Circling into punches, like hendo vs bisping, erm lazy judo throws, you know when they try the throw but fall flat on there stomach cause the other guy is to strong or something.
Also there is various ground techniques like meat hooking a guy from out of guard into dominant side control.
The wizard is a cool sub, not sure if you guys heard of it, very very rare though.
Catch guillotines but think you got one.
Watch sakuraba fight you will find a lot of great catch wrestling techniques. Which reminds me ground strikes from guard like his double hand slap on either temple, you could have "so and so feints a left hand from guard only to pull back with a vicious right hammer fist to the chin.
They might suck or help you, hope they help. But just a few suggestions. Some you probably already thought of yourself if not all of them
