Yes! I would recommend getting one because first of all, it only costs about $50-$80 on ebay, which is a very good price for a duelist pack. Second of all, my brother has one, and he wins with it just about every time we duel! Just keep in mind that you aren't guaranteed any certain card in duelist packs. This means for example, if you want a crush card virus in the kaiba duelist, you aren't guaranteed to receive one!
I would say maybe kaiba duelist pack, because you have a small chance to get a crush card virus. There are also a bunch of other strong monsters which can be easily summoned thanks to cost down, which you have a chance of getting in the kaiba duelist. Or yugi duelist, because you have a chance to get mirror force and sorcerer of dark magic, which are powerful cards!
The card Dragon Master Knight came in the booster pack "Duelist Pack: Kaiba".
He is in Invasion of Chaos, Dark Revelation 2, and Duelist Pack Kaiba. He is also a promo in The Lost Millenium's special edition pack.
Tens of thousands in the original Ultimate Edition Series 2 promotional pack, and tens of thousands more in Duelist Pack Kaiba.
Here, they cost £72 UK, but many stores give a 10% discount if you buy a full box.
for the original promo, around $10, for the duelist pack kaiba it was $6, until recently it's price rose...
