Ok im fairly new to this game and finally got ahold of pretty much all the cards i wants and was wondering if you guys would help me build a good deck out of these sets i have.

i have the whole Vortex set except the legendary and i have the whole Jungo set except legendary and i have the whole Nightmare set except the legendary.

thanks in advance any suggestions are really appreciated like what dual deck i should use or mono Nightmare ,Jungo or Vortex. thanks !!!

Those 3 clans work well for halfsies.
imho just check around for available public presets, they can give a good preview into what you can do with your cards

i'm not too experienced with more expensive cards myself, but perhaps:
Jean Pegh Mindy/Radek Ongh/Askai
C Wing Neloe Deea/daag Oflgn/Dregn/Naele
Artus Bill/Mawpin Oshitsune/Pan/Edwin/Azgroth Karrion/Kolos/Ghumbo

Survivor Elo
Pegh, Jean, Radek, Ongh
Karion, Artus, Pan, Edwin or C Wing, Deea, Dagg, X-0DUS

Survivor Type 2
Ongh, Askai, Zornado
Karrion, Kolos, Ghumbo, Oshitsune, Amber (Morphan, Eklore, Eyrik or Hugo if you can't afford)

Elo
Ongh/Troompah, Niva, Rodney, Radek, Nyema, Bhooma, Jean, Pegh
Niva, Nyema, Radek, Jean, Dregn, Deea, Qorah, C Wing
Dregn, Dagg, Cyb Lhia, C Wing, Karrion, Edwin, Pan, Arus

Those are my choices, you can decide based on preference.
