I have a better idea for the tactics card.
1st, the positive and negative effects of each card should be on the same matter whether GK, DF, MF or FW
2nd, the duration is variable from 5-45 minutes to fit with more strategies and/or the match status
3rd, the card effect could be stacked with each other to create more thrilling and challenging gameplay during watching real matches
What daya think about those above? Let me know your ideas
