Kind of a special scenario here. I did my research about the grind wall from 155-165 and how you should save up your lvl 7 and 8 cards and use them to get from 165 to 175+.
the questin is, what if I have enough 5 and 6 cards to get me to 165? would I still need to save those and grind to 165 instead? I know saving them will give me a slight advantage and I can use them to fi the gaps here and there but would it be necessary?
is there any special reason to grind to 165 other than saving those 7 and 8 cards?
