"I got tired of seeing the clan bonuses being the winning factor so i shut it down."

The point is that there are cards and combinations of cards that care nothing for your SoB.

Jackie and Zatman both retain awesome potential without their bonus. Jackie shutting down the abilities that both SoB clans rely on, and Zatman retaining 8 power and -4 attack for a 3*.

The Tan Man is still 8 power and -2 damage.
Jackie Cr negates SoB entirely.
Kolos doesnt' care.
And so on...

There are hands that simply dominate the mode.

Bangers dominate T2, I've noticed.

Nightmare really have a couple of good low star cards going for them nowadays
and with Raeth and Selma out there, backed up by they ever annoying Smokey and Hawkins..
Uppers can really have a hard time..Tyd is a perfect Jacky stopper
if you only know how and experiment
see how people react to them

I absolutely agree that Zatman and Jacky are one of the most destructive combo's out there
backed up by cards like Rubie, Oxen and Dorian, them become more than a nuisance

but playing Kolos or any of the big five comes with responsibillity
comes with experience, you can't expect a card to win for you, now can you?
