Actually..no need for banning see if a poll occurs of banning of couple Ulu Watu characters the balance will tip over for another clan then another person will whine..and make another post of banning about another clan and so on and so on...besides if you can make a deck of stopping ulu watus clan bonus and character ability you shouldn't have any problem winning
This kinda scene reminds me of another real life collectible card game. Ban this, another will pop up, ban that, yet another will pop up. It will never end, IMHO. For me, I think building a deck to handle those deck will be ok but at the risk of losing to others.
