For the guaranteed copy from War Chronicle event, just play every day and spend enough AP in order to trigger the WC event (10 or 30 AP). Now you have to choose the difficulty level (3 to 5★), then the enemy type. If your team is enough strong, try the higher level of difficulty because first you can retry if you fail ; and the rewards are better.

Not tested: If you missed a day, each daily extra WC event try will cost 100 rings. I'm not sure but this should help you to drop the guaranteed copy (to be confirmed).
