But... Its not that hard to remember what they do. It took me like 5 minutes. I looked at them, labeled them by colour, went into a fight and pulled Arrow and since its blue I forgot what it did exactly (between that and the Spear), so I checked again and was like "Well, their names make it easy" and since then I've remembered what they all do.

It would be helpful for everyone else who doesn't know, but imo it doesn't really matter because you are playing it on them and they should just accept that.
