Dragon Dive is a build for koga that makes him more susteinable, with adrenaline junkie you're gonna use and abuse of the shadow step, and for that you receive 300 health each time you use it, if you're cauterized, only the first shadow step you do will be applied, in the start of the match we can say that the koga with this build has 900 more health, in most of fights you'll use the submachines to deal the most damage, staying in the smg most of the time because this way you play safe with the shadow step even escaping enemy ultimates like Lian and Zhin. With Unyielding you use less energy in claw stance and you can save that energy you have to more shadow steps. Something to Prove is the best, almost a must have in LEVEL 3, because this simply gives you a 1 free energy bar. The level 2 Swift Hands is the one you gonna need, because the delay in entering and exiting the claws is troublesome, you can try having this card in higher levels but this loadout is one of the bests in my oppinion, the level 1 card can be almost any, I use Triggerr Happy because cauterize is annoying.
