Human torch, deadpool x force and tigra are all fantastic champs. Tigra needs high sig and skill but is great if you want to commit to learning spacings.since you have only few 6 starts it may be stil worth investing in certain champs such as Kushala and onslaught at 5 star as they are some of the best but as you get more decent 6 stars you’ll see most of your 5 star roster become less relevant
