Duel master tcg..

An english speaking guy here on ETCG is very rare, interesting. But, first off: welcome to this board.

To answer your question: Well, Duel Masters isn't quite "in" at all. In fact the production of the english version of this trading card game was cancelled in 2006 if I remember correctly.
But Hasbro/Takara Tomy actually is working on a rerelease of this Cardgame which will be called "Kaijudo". It will have a completly new Card-layout, and it will even have some creatures which the japaneses Version will not have (Like Tatsurion and Razorkinder). But it is to early to tell, if this new version will be succesful because it has very strong competitors in its segment at the moment like Yu-Gi-Oh!, Pokemon, Magic The Gathering and the very new Game called "Cardfight! Vanguard!.

We have for every one of this Games at least one Thread here on this board if you want to know more

P.S.: I hope you could read my english, I did kind of rust since my Schooldays XD"
