You'll see Jackie, Zatman, Dorian, Oxen, Rubie, and other Uppers really often in Deathmatch. Now I'm starting to wonder if STOP cards will work, or maybe even a deck to counter a typical Uppers DM deck. (And the STOP cards can fight GHEIST and Roots, too!)
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?
