CARDS YOU CAN'T USE IN YOUR DECKS! MUST READ!

[Tyranno Hassleberry]

D-Heros-Aster's father created them yet they wre never relased
Blue-Eyes-only kaiba can have these since they have the only copies
Neos-Jaden created these, currnely in space
any sacred card
FGD-only four copies of the card, Kurai has three, while Zane has one
Toons-since only Pegasus has them
Chaos Emperor Dragon banned from the school

more when I think of them
