I have a lvl 15 griffi knight, and two lvl 10 griffi knights (with no runes and not in decks) I would like to use the lvl 10's to meld the lvl 15 but the game does not recognize them, any suggestions?
Yeah been thru that too! Make sure there's no runes attached, they are not included in any of your 4 decks or 3 tourney decks, and they're not locked. Then they'll show up. But if you already evolved a 4* card you cannot use it as a duplicate! 5* cards can still be used as duplicates when evolved, but not 4*... hope that helps!
