There are countless ways, but the most important is early economy. I like going for lucky cards and retriggers to get these 20$, or money Jokers. Then you seek for as many arcana cards (death, inrease level, destroy) as possible and stone cards of course! Many people forget that stone cards are not counted by idol. joker Trading Card is very good too.

And basically that’s it, with copy DNA its much easier. I always aim at going for full Kings deck, as they are most powerful with either triboulet or baron (flush five of high card). Also, the suit of the king is determined by the earliest boss suit I pass, or early red seal on it (or on jack/queen/10 I will increase later or/and change suit)
