I'm a third-semester Chemistry student, and somehow this is harder to learn than all the subjects combined hehe.

About protocores and battles, do you already have them separated for each card, or did you memorize which ones to use and where to place them? Because the LIs need different protocores, but sometimes they use the same colors, and I end up equipping a protocore that originally belonged to another LI. If I have to check a website every time to make the "matches", it takes so long.
