Yes great pachinco 10x is very good, because you can use what you want and can sell what you do not need.
But the best option is to sell even more rare. and stay only with Rare affection XP like sayd Greetings, to raise Affection revenues from girls early.
I think with this drop rate there are guys using épic pachinco 10x because girls are guaranteed with this.
I saw one guy at arena with the 3 Ninja Spy girls Affection LV3 OMG.
