You could also go Balthaza, Fire, Perplex, Nightmare, Monk, water, Undead, Pirate, Strength, Hoelbrak, Flame Legion I could go on and on I have done some many combos and so many things work great. Just really depends what role you want to excel at. Making new builds and set ups is really enjoyable, only due lack of time I have stopped doing it.
