I am a level 16 and quite new to this game.
I have 400 clintz and 19 credits from rewards. I am making a skeelz deck and have these following cards.
Hugo , Timber , Vansaar , Sol Hona , Cley , Danae , Deebler , Drake , Zeke , Sandro ,Otto , Greem (my most favourite in my collection)
I-suicide is right you should have started with a montana since the montana clan is a money making clan good for DT's and not that expensive too..
well since you chose skeelz this can be my advice.. you already have 3 good cards in mono skeelz namely danae, sandro and zeke.. might i suggest you buy redra after you won your credits.. that way when you open another boosterpack you might get another skeelz card.. as much as possible work your way to buy cheap cards first namely eloxia or dwan as stated by CardzRuler before buying those expensive and crucial ones namely sasha, chiara and Praxie..
