while starting a new deck my friend and i couldnt remember the name of a card or find it while searching so i switched to their account to look for the card since they owned it. when i went into their deck builder it said resume editing my buddy didnt remember being in the middle of deck editing but i clicked yes so we could check what it was referring to. my partial deck had appeared on their account and showed that they owned the cards in said deck which they did not. I then checked my account and could not find a save of the deck on mine. once again i log into their account and it shows the deck but correctly shows that they do not own those cards. i tried duplicating to send the deck build back to my account the same way and it worked. however when it came back to me it showed that i did not own those cards. after relogging it had corrected that issue. so yeah just wanted to tell you about it swapping decks from one account to another if anyone logs on the same device while mid edit. thanks for all the hard work : }

Update; it happened again on my Samsung phone. No one else logs in on my phone. Resume editing popped up & cards I wouldn't use were in a deck on my account. I can't explain this please fix it.....
