Its an anime or something around that area about these 2 guys that can turn into cards and ones some guy that controls water through his hands or something and the other I can't remember about him but when the cards are combined they turn into this ultimate dude?? Its really old show but its been bugging me for years now +P

Sounds like the series,.

Shinzo (2000)

It kind of looks like it I'm not to sure cause its been a very long time lol but ill definitively look into this show if it's the one thanks.. is there any other ones you know like that?
