well, special practice costs are 6k G for N cards, 15k G for Rs, 30k G for SRs, and 45k G for URs--

if it's not the money problems, maybe it's the one Lucia said-- If the card you're going to special practice with is "locked" or is a "favourite" card, then you really can't idolize with it-- since making a card a favourite prevents it from being accidentally practiced off or sold- so better remove it from favourites if you want to perform a special practice with it--

if those don't fix the problem, then i dunno what else could be the problem ¯\_(ツ)_/¯
