If money is not an issue, then you should ttry GHEIST, Pussycats, Roots, and for tournaments, Montana and Uppers for sure. They are the main clans to use if you want to play good games, and you always need some strategy, build your own deck and have fun
Maybe try a Mono/Leader deck like Nightmare, La Junta, Fang Pi or Piranas and Ambre? Or Junkz/Uppers/Montana/Sentinals/Rescue/Hugo. Or Ula Watu/Bangers/Morphin. I prefer them to the two clan decks because you never get 3/1 screwed. You can even throw in a cheap powerful ability low star card like Veenyle/Hawkins/Uranus/Smokey to any of these and still always get the bonus you were looking for.
