SWCCG is king.
After that, I'd recommend ST2E if you enjoy more thinking than playing, and ST1E if you prefer thinking *and* headaches.
.hack//ENEMY is all right up until the third set (it nose-dived after that); Wars TCG is also acceptable, even though there are very few cards to play with. Young Jedi and Jedi Knights are niche games, the former geared towards younger players and the latter... well I've never actually played Jedi Knights so I wouldn't know.
Don't waste your time on Beyblade or MegaMan.
Oh, yeah... Austin Powers is shagtastic.
