I hear a lot of people complain about how much this game relies on P2W but with Devs adding new fusions that are epic yet on par with many legendary cards and with the event drops, i do not see the problem. Some of the most common cards I see these days (and im lvl 24 in a top 15 guild) are the Slick Garroter, Kor Infestor, and the Xebor Comet, all of which can be obtained by the average player by putting in some time to acquire the cards for fusion/ upgrade/quest completion. This is not a game that you will become high level/highly effective in on day one, it takes time but all good things do.
