Instructions
Play the "Single Player" mode. You need to play against a computer opponent and win at least once before you can get this achievement. This is because you need at least one card that isn't already in your deck, and you receive new cards by playing against computer opponents. It generally doesn't matter whether you win or lose.
Go to "Deck Edit" mode after you have won your first match and gotten some new cards. Select the "Trunk" category. This will list all of the cards that are in your collection. Select the card or cards that you just got.
Change the Category to "Deck", which will open up another menu. Choose "Select Card" to add the cards to your deck. Then scroll down the menu and choose the "Edit Recipe" option.
Select the "Edit Recipe Name" in the "Edit Recipe" sub-menu. Rename your new recipe to the name of your choice. Then select "Register Recipe," which will save your selection. Exit all of the menus, and you should have earned your achievement once you get back to the title screen.
