Pro tip #1:
You need a Google account to authenticate into Deck List Creator. You can use a non-Google email if you'd like, but you must create a Google account with it. For more information on how to do this, head to https://support.google.com/accounts/answer/27441.
Pro tip #2:
Add a comment to each saved deck list. This can be a deck list name, which tournament you played it, or anything that is a good way for you to keep track of your saved lists.
Pro tip #3:
Register with the same Google account email that you use to login to Deck List Creator, and your registration will be automatically linked!
Pro tip #4:
Don't wait until the last minute to submit your deck list in case you run into a challenge. You may resubmit a new deck list as many times as you'd like, up until the submission deadline.
Pro tip #5:
Know the information you need to submit your deck list! If you need to claim your registration, you will need your registration number from your confirmation email.
Pro tip #6:
Check your email and the TCG Live Roster for your tournament to verify you have submitted your deck list successfully. You'll receive an email after a successful deck list submission that shows the deck list you submitted. We highly recommend reviewing this email to make sure that your submitted deck list matches the deck you plan to play. You'll also appear on the TCG Live Roster with "Submitted" in the team list column.
