Well this took about 3 hours to get sorted. I decided to do 4 sets of cards to let me allow 4 players at once.
Really pleased with the results. I was going to laminate them, but that will take time away from sorting out the arena.
My life would have been easier if I could have printed on both sides rather than having to do a side fold type which was then glued together.

I will probably sit them under a couple of heavy books to flatten them a bit more. I decided to decorate them with original mosaics. Each player gets a different set.
