When I was newbies; I could not find any guide to accept me to join. some of them ask new member to pay DEC as the entry fee, but most of the entry fee is kinds of expensive. My suggestion is collect more card and do more battles to learn how to fight smartly. You can try to apply any guides if you are interested in. Generally speaking, if players don't have potentials or pay DEC for helping build guide, those players may get kick out soon. Anyway, some guides are really friendly; there may have private discords or communities to communicate or help each other.
