Breeding

[Xandor]

What is the easiest way I can get good passives on Beakon?
I have Beakon with Ferocious passive (20% damage). I want Vanguard (end game guns deal insane damage) and Musclehead 30% damage. I would like to get Legendary also but not sure if it is possible to get it on Beakon.
Swift would be a good option also.
I think I have 40+ Beakon now and only got Ferocious so far.

Either way I am currently breeding my Beakons nonstop but I am only getting useless passives, any idea how I can make sure it get good ones? I know I can mix types to get good passives easily but I want the end result to be a Beakon so not sure if that works.

Also does it lower change to get one of the other yellow passives if I already have Ferocious when I breed? Should I breed ones with no passives to have higher chance to get a yellow passive?
