Notation on Helm Breaker x 2 variants

I was looking for some variants on the combos I see that involve doing Helm breaker twice. I feel like that would be a slightly better bnb for me starting out. Thanks!

When you say that you see the combos, where do you see them being done…and can you tell me where i can see them. If i knew what you’re talking about exactly, maybe i can try to help.
