Top Tier Attack Type

Hey guys, I know I should probably post this on the "Build me a combo!" thread, but could someone please tell me (or the people who wanna know) what the top tier attack type is?

Idk if its top tier but I have MF Lightning Ldrago CH120 HF/S (Hole Flat mode)
... Look at the Competitive Metal Fight Beyblade Combos topic.

HF/S is not a top-tier part.
