You need a 3* card in that empty slot to craft it to the next rank. I have the same issue, and it's keeping my Force strike u at rank 1, lol.
Just buy GUROTO at s coin shop to upgrade 3 star card
but the cost was 600 s coin damn so much
that card is consider one of easier card. There are some card that requires two 3 star such as strike force card. Be prepare for two guruton card...
What AR card key do I need to craft strike force card?
