What is the best character card combination?

I personally use:

Hayato DA Zero(DS if you don't train)
Xenon Mech Shade(please, even if mech sucks ass, please make one, 15% buff is so useful, and you should have xenon)
Kanna Tamer MM(Merc for cooldown reduction, or mage for lolmageset)

I swap in Kaiser when I'm training link skill mules.

Also, you're using Paladin. PLEASE FOR THE LOVE OF ALL THAT IS HOLY take it out it sucks seriously
