Better Performance Cards Setup
Good day. First of all, I wish everyone who are participating in the ILLIT GLITTERDAY event all the best of luck!
I would like to ask a question. It's sort of answered already in one of my posts before, but I just want a clearer answer and justification. My main group on the game is ILLIT. My current Performance Cards setup is full Lv. 60 UR WITH Ver. - I'LL LIKE YOU (photo 1). I do know that using a higher tier card will give me a higher score in gameplays. Currently, I have higher tiered cards for each member (GLITTERDAY Yunah XR [from trade] and Moka A [from card pull] cards; ILLIT Deco Polaroid Moka Max UR card, Arcade Rush Minju and Iroha A cards; and Night Bloom Wonhee A card) (photo 2).
I have this mindset that I should complete the theme first if I want to use it, that's why I haven't used the higher tiered cards since they're all different themes. My goal this week is hopefully complete the GLITTERDAY theme through card packs and trades. I just want to ask these:
Would using the same theme for all the members will give me a higher bonus or any perk compared to just using any card regardless of theme?
Would I benefit more from using higher tiered cards even if they're not the same theme?
Any insights and/or responses regarding this would be highly appreciated. Thank you so much!
