1 fight every 5 min is very little. I only play a match for 5 minutes when I play against a GraksmxxT + Uranus noob
Dr Van Wesel Ld, Rolph, Toro are not good enough for T1 DM
Play with low star cards with high damage, like Lance, Arkn, Randy, Oxen, Jackie Cr, Spyke, Mechakolos, Copper Cr (of course you can use cards like Hawk, Saki, Zatman, Lehane)
If you want to keep GHEIST+Riots I would advise
Mechakolos, Toro, Arkn, Z3r0 D34d
Pr Hartnell, Molder, Reeplay, Boomstock
I have a good deck for 56k. works for tourney but is probably good for death match.
at least have a look http://www.urban-rivals.com/presets/?id_preset=2755103&list
I managed to have a score of 460 using a Nightmare deck consisting of Kolos, Ghumbo, Oshitsune, Azgroth, Nistarok, Karrion, Kenny Cr, and Ambre.
Too bad if the enemies think that they are losing and know that you're at the top with a very large point already, they purposely maximize the time on picking cards to eat away your time in order for you to have less battle, therefore less points. Happens to me every time.
