Interesting online spreadsheet that does auto calculation to build best club war attacks from existing war items of a player.
https://docs.google.com/spreadsheets/d/18zqCS_9k7rl1-53jdZUEv-gE80rOmka9Neru0MiGKc0/edit?fd=true
Also some video guide/tutorials are online but that spreadsheet link is demo and shared and generally someone is using it but its supposed to have free exclusive access version too!! Anyone try it yet?
PS.
Seems above link is not working in my tablet. I am not sure how to create these links. However I can login just fine, from link given in the description of the user instruction video
That link opens the spreadsheet in in my tablet in 'desktop' mode, and does not require any downloading of Google Sheets first.
