What's the point of take two deck codes?

[Nine]

I copied a deck code from take two since I finally got a 5 win run and I wanted to save the deck, but then it's like "this deck is for take two and can't be used" So like, why is there an ability to copy the code anyway

Maybe so you can use it on t2 private matches or to put it on card builder so you can show it to other people ? I dunno,never paid attention to that button either.

Thats strange. I had assumed it would just make a list you could turn into a deck if you had all the cards used. However i suppose not.

I now have no idea what thats supposed to be.
