Hi! I'm at level 70 and only been playing for 2-3 months. I used to keep r cards to level up and use in elemental halls, but by now most of my attack units consist of SRs and up. I've been getting rid of my R cards to focus on maximizing cards with high attack/good skills, but I was wondering if there are any R cards that amalgamate into something good that I should be saving. I tried finding a list on the wiki, but couldn't find what I was looking for. Does  anyone have anytips or should i just continue recycling my R cards?
