OPO Deck Builder Suggestion

[Skeletaur]

I wanted to say how amazing the OP Deck builder is. It really helps! Thanks a lot for the great work!

I had one idea: I feel it would be cool if a new version of OPO Deck Builder came with a personal checklist ability. You can enter the # of cards you have. Then you would have a checkbox to select "Use only cards that I own". It could also have the ability to export an excel or txt file with your collection. What do you guys think? (Sorry if Its already been suggested: I took a look and didn't see a topic on this"
