Need help to clear 6.1.2 sentinel

Bleakmess

My hyperion alone takes me to sentinel but I couldn't pass through sentinel, I tried colossus but he is at 3/5 and cannot outrun regen. What other champ from my roster can be used?

You can rank up colossus or rather wait for a better double immune champ like iceman,omega red
