Who to rank up next...

Looking for opinions on my next rank up, leaning towards Gulk, scarlet witch, or Iceman tbh. For where I am in the game, I am not uncollected yet (my next goal), but I have completed ROL. My AW teams are solid, so not necessarily looking for a good defender/attacker, but if the champ does that as well that'd be nice.
All my 5*'s are unduped.

Sorry there's so many options, I'm kinda stumped as to what would be most useful

GR is amazing as a standalone champ. Very sustainable and can hit hard.

I would do SW

Emma frost is definitely the best out of all of these, her being a 5* and with all of her usage. She's one of my favorite champs to play.

I hear act 5 has a lot of debuffs so Iceman's immunities should help a lot. Scarlett witch is also good.

Gulk has plenty of niche uses. He's not the best for most things, but what he does excel at he does better than the rest. He's a great champion when it comes to rounding out your roster.
