Simple, make a cheap Fang Pi Clang / All Stars deck to start with,
Windy Mor *3
Xia Leming *3 (300 ctz)
Striker *4 (1700... try to bargain for 1500)
Frank *2 / Ashley *2 (130 ea.)
There are better builds but since you are new, try to save all your money to get a Striker, play daily tournaments and save save save, only buy Action packs and update us once you get your new cards from the shop. Good luck!
