Yeah, Taker started actually wrestling in matches with the likes of Mankind and Bret in '96-'97 iirc.
But in retrospect, Ministry era might just be peak Taker as far I'm concerned. One of my favorite episodes:

Besides the unforgettable scene of Taker calling in a hit via his Motorola flip phone (Don't you fail me, Mideon), his exchange with Big Show at the end is actually pretty intense. Show was over!
Undertaker really sold well. Seriously, lots of big man who have to no sell because it's the character choose not to roll their head at all. Taker would take these wild staggers while still giving off that he was merely stunned momentarily. I noticed it even as far back as his match with Hogan at SS '91.
