What does that mean? You want a Defense/Stamina combo, or you actually want something to beat beys in a Defense/Stamina meta?
As I did not understand your question, I'll give all the combos possible.
These are supposedly your best bets-
Hey, wait...
The combos we suggested to you before are the best pre-4D combos you can make.
Otherwise, IIRC, the best were-
Attack- MF Lightning L Drago BD145LRF (Now referred to as being overrated)
Defense- MF/MF-H Basalt Aquario BD145CS (Superb combo)
Stamina- Hell Kerbecs BD145WD
