You couldn’t do wrong with a couple of choices. Colossus is so amazing after his buff that he’s mostly definitely worth it. Venom is also a great contender along with stealthy. I would say narrow it to them. I have a 4/55 Medusa and don’t use her that often at all. She just helped with v1 and act 5 100%. Gulk is a little too niche for my liking
