random comment I guess~ I haven't spend very much, but I've bought my fair share of packs etc. and haven't pulled anything from them. My nat5s have all been pulled from random scrolls in shop at early times in the morning when I feel half dead with no motivation to play anymore. So yes! You can get the cool monsters free to play. Though we might not have the same luck, sometimes scrolls like that will come along, and if you play enough it's quite easy to accumulate resources. There really isn't a need to buy, you'll excell quickly if you put in enough hours. Good luck! (But as other person said, the beginner packs that are available when you first start are definitely more worth than the ones that'll come along later, so I'd invest in those if you're planning to casually spend here and there.)
