Forum:World Championship 2010 cards

I'm trying to get the 100% card completion on Yu-Gi-Oh 5DS! World Championship 2010 Reverse of Arcadia. So far, I have unlocked all other 49 packs and gotten 100% in them, I've gotten all but two structure decks (Water and Fire), and so far, I have about 3,460/3,470 cards. How many cards do I need for 95% card completion to unlock the last booster pack, and are there any codes to input cards (y'know, in the World Championship section), and exactly how many cards are there altogether in the game? Any advice or tips is welcome, I know I'm asking a lot.
