So. Rn I only have two of them, waiting on wizard rod which will be next month.
My beys are:
Soar Phoenix 3-80N made by using helm knights rachet and bit with soar Phoenixs too

Helm knight 3-60 rush. Uses sword drains rachet and dagger drans bit with the top being helm knights

I would recommend taking a peek at the Winning Combos thread to get a better idea of what to build, or making use of the Build Me A Combo! thread. But to answer your question here, I think these two will struggle a bit.

Phoenix is a heavy, high-recoil blade. It's still incredibly good, too. Its best use case with what you have is likely Soar Phoenix 3-60 Rush. Strong attack type with solid stamina. Putting Needle on a blade that aggressive will result in losing outspins to stamina types and getting KO'd by attack types. All without being able to generate meaningful KO power itself without help.

Frankly, Helm Knight is not very good. There aren't really viable parts anywhere on it, so your best bet is almost certainly going to be playing it stock until your Wizard Rod comes in, at which point you will likely be playing that stock.

I like it, but I think that helm knight would be a better stamina type
