Okay what I'm trying to do is make it to where I can challenge Jack and Diamond in the end game with normal rules. For some reason, Diamond always plays with stuff like Random, Plus, etc.

Here's what I've been doing... 1.) Win Quistis card before Fire Cavern. 2.) Right after Dollet mission, change rule to 'Diff' using Queen of Cards, then win Zell card from his mother. 3.) Get magical lamp, beat Diablos. 4.) Battle Cid and kid running in lobby for Seifer, Mog, and 15 battles total won in Balamb Garden. 5.) Go through CC Card Quest on disk 2, spawning "King" in my dorm after making rules normal with Dr. Kadowski. 6.) Challenge Edea after the letter to White Seeds until she doesn't want to mix rules.

At the end of game, Jack plays Open/Diff, but Diamonds plays Random and all kinds of dumb stuff.

I want to know what I'm missing because it's annoying the crap out of me getting to end game and not being able to win the cards.

Thanks.

The 100% notes (found in the guides section) have a few very important sections that involve card rules and are key in removing the bad rules from the Trabia region, which is the region Diamond uses for their rules.

1. Remember that we have to play a card game in the Galbadia Prison to get the Character report
2. Because of 1), we have to restore Balamb rules, which we do after Oilboyles before we play vs CC Jack. This means that you have to decline to play cards until the person doesn't want to mix rules anymore, then they will only play with Balamb rules.
3. The first time we visit Shumi Village (which is in the Trabia region), we are carrying Balamb rules, so we can manipulate the rules. After a hard reset (Save+Quit), try to play cards against anyone in Shumi Village and decline 8 times before accepting the game. Then when you enter the card game screen you can exit and the "Plus" rule should be removed.
4. Before the next time we visit Shumi Village we want to be carrying Centra rules to be able to remove "Random". We get them by asking to play cards vs Edea at her house until she doesn't want to mix rules anymore. At that point we are carrying Balamb rules because we have taken them back from Dr. Kadowaki at the start of Disc 3, I'm not sure this is essential, my memory is hazy on this bit.

Once you're carrying Centra rules you can do the same as above and ask any Shumi to play cards but now instead of declining 8 times you only decline 4 times, and then accept. This is again done after a Save+Quit.

And that's it, with two visits to Shumi Village and some clever abuse of card rule manipulation you can remove the two most annoying rules of the region and now Diamond are left with no rules at all. Sometimes when you go from playing Jack to playing Diamond in the Ragnarok you can spread the "Open" rule, but definitely not always. It doesn't change much though if you have a good and consistent strategy for the card games.

Good luck!

Hey thanks for detailed reply!

Based on that, now I know what I was missing.

My issue was that I wasn't doing any of the card manips in Shumi Village. If anybody else is having trouble with getting card rules sorted out for the end game, I hope this post helps them, too.

By the way, thanks for making the PC 100% run notes. I notice you're the creator of those. They're very helpful.
