Add a text highlight for card effects which are currently used. (in case the card has multiple effects).
With this some may understand the card easier and learn which effect they use.
For example in Master Duel:
I know there is already a pop up telling what it does but it does not go in detail, which might be important.
In this case it does not mention that it fusions the cards from the Field, GY … and returns them into the Deck.
