Why haven't Blade been an Avernger or X-men or SOMETHING?

Would you like him as one? Would you read an ongoing book? It doesn't have to be about the Avengers or X-men, I'm just saying like a regular title. For a character that had an amplitude of media exposure in the 90's- early 00's, in the Blade film that jump started Marvel's Cinematic Universe, there sure hasn't been much else done with the character.

SHhhhhhh....That animated TV series never happened
