I made this modification of my remix of Bigal's edh tray as it was a good size and usability, but I noticed that my friends were breaking the text off of theirs so I made a version with debossed (embossed?) text and a cleaner design. I also made life counters that fit into the life slot and are very easy to use. Have a look at them here.

Also: if you download my design and print it, please give me a like and submit makes!
