Sentry or Sentinel from deadpool store (non-BG)
I’ve heard good things about Sentinel, but it usually is more in the context of being a tough defender (which seems like it requires a dupe?). But some people do like his damage output.
Some people like Sentry for longform. I do like the idea of a Science champion with buffs and nullify immunity. However, i don’t currently have any everest content left that calls for a Sentry.
