Character Card System

Can anyone recommend me a Character card set that would suit Eunwols?

Set 1 pirate set:
Mechanic for buff duration
Xenon for stat
eunwol for min crit

Set 2 nothing special:
Kanna for boss dmg
Beast tamer for ignore def
Marksman for critical (this isnt so useful for bossing, past 50% hp you will crit nearly all the time)

set 3 warrior set (I know it sucks but its a free bonus):
Da for boss dmg
Hayato for minimum critical dmg
ds/zero/kaiser status resist/exp/stat

There are probably some better options, like if you dont need status resist ds will be useless, if you dont need crit past 50% hp marksman will suck & if you dont grind zero isnt needed either. Im not sure if corsair/jett card works with the copy skill that eunwol has aswell, if it does, then get both of them aswell.
