In FFVIII lose any card that you want more then one of, then win it back. When you go into Time Compression you should be able to get that card again even though you've already won it back. Also, when in Time Compression, you can challenge some of the CC members and get some level 8 cards that you already have. Now if you didn't have the chance to get all of the level 8 and higher cards before Time Compression then you should go visit The Queen of Cards in Time Compresion. If you already know where the escape pod from Lunar Base landed then just go there. If you don't then follow these directions. First you should get the Ragnarok. Then go South of Tear's Point just past the fence. (I suggest using Enc-None if you have it) Then just walk around until you enter the area where the Queen of Cards is and when you challenge her you'll be able to win any cards that you haven't had a chance to get but she has the Random rule, good cards, and is rather good herself so she's a tough opponent.
