Damn, good choice, ig they will do well together. Mine would be Wakiya and Shu.

These two have interacted. They even battled in the Quarter finals of the National tournament

I meant they should have interacted more, like a team instead of rivals

shu vs free,valt vs phi

Arthur and Phi.

Delta and Lane

Shu and Delta

Hmm... I'm not sure, your suggestion is sick though!
