So I have a spare uncap crystal here from doing some old Master's Challenges. I am still using some pretty outdated cards in my deck like SPD Dura and INT McQueen, but they're fully uncapped. Meanwhile I have 1LB Ai-chan, 2LB STAM Shakur, 1LB STR Tamamo, and also 0LB INT Rudolf for the current meta cards. I heard that the new GUTS Stego is already good at no upcap so I am removing that from the options. Where should I use this crystal on? I wanna make sure I don't waste this.
