Yugioh: If you chose a...

[seiryu]

I would choose Sky Dragon of Osiris (I don't know what it's called in the english version, nor do I really care) because it will lower a face-up monster's points by 2000 and if I bring it out to the field with enough cards in my hand it will rock the field.

or the Chaos Emperor Dragon, his effect could be even more dangerous if he was my deck master (that goes for the Chaos Soldier ~Messenger of the Beginning too) XD

well, 1) I don't really play Duel Monsters anymore and 2) the whole Deckmaster thing is a load of bs, it's pretty much you just choose a monster and make up Deckmaster effects. It was never meant to be used in the actual card game, and I don't think it ever will.

I don't have the actual Osiris card (my friend does), but I do have the Collossus of Obelisk (I think I spelled collossus wrong >_<) and Winged Dragon of Ra, the actual REAL Japanese versions, as that's the only cards that I ever used. Everything got screwed up in the english version, and thus I don't use those names since they're completely stupid.
