Dream Battles

What are some battles that have either:

1) happenned in comics already and u want to happen again?

2) or have never happened and u would like to see?

I wanna see Hulk and Juggy go at it one more time.

I wanns see Sentry battle a worthy foe, someone he can go all out with. I wanna see him really fight Galactus, instead of hearing it from Spiderman. I wanna see him battle someone like Thanos or Mephisto. I wanna see him battle the guy he replaced in the Avengers, Thor.

i would like to see classic magneto and current storm go at it

I also wanna see the Ultimate Versions of the Thing and Hulk go at it.
