God Cards:
----------
After winning the Expert Tournament and get the title of The King Of
Gameslook for Ishizu at the West Town Zone once you find her, she will
make you battle Kaiba in a single duel; if you beat him he will hand a
God card to you. If you choose Wisdom he gives you Slifer The Sky Dragon
and if you choose Power he gives you Obelisk the Tormentor.
Ra:
---
You must progress through the game until you get the Marik. After you duel
him a lot, and if you have either Slifer or Obelisk in your trunk, he will
ask to trade you for his Ra.
Game tip:
---------
When going to places in the first city, like the shop, time can be saved
by hitting the Home icon in the bottom-right corner. For some reason,
this doesn't cause any time to pass, and allows you to get much more done
in one day.
Automated Loss (Slightly bad):
------------------------------
During the expert tournament, if the player who's view is yours loses
(Joey or Yugi), it counts as a loss on your own record.
