iii dont know :p
Yes, after the expert cup you can get it from Ishizu.
No, Raviel, the Lord of Phantasms is not available in Yu-Gi-Oh! Nightmare Troubadour.
yes there is it is 268756875645985689
You could play it on both. Any DS game can play on your DSi
either trade from nightmare troubadour or use an action replay (don't know the code though)
You get to level 22 and beat Yami Marik Then you will have all packs available however some cards you have to trade to get.
Go to your room and then press on the box above your head.
Unfortunately, no previous YGO! DS games can link with World Championship 2008, so you cannot get the God Cards from Nightmare Troubadour. I know for a fact that "Slifer the Sky Dragon" was offered as a downloadable card for one day, so perhaps that is the only way of getting the God Cards. yes ghosts exists.
yes
If your talkin about real life cards go to tescos OR if your talkin about yugioh nightmare troubadour, you can buy packs for 1000KC.
I am also looking for this code but so far it seems s if there isn't one so sorry
After beating the expert cup search for Ishizu and you'll have to duel for it. (When I played I had to beat Seto Kaiba for Slifer the Sky Dragon). You can only have one god card at a time unless you use Action Replay cheats. You can trade the god card you get for the one Yami Yugi has or after beating the game you can trade Marik for Ra.
