i played through a couple of the betas, it's pretty good. a fair bit more in depth than 'legends' but also slightly more grindy.

it's a completely different game from 'legends' although it does use some of the same art for the cards. initially it was only meant for china i believe, to possibly replace legends. some of the legends community members i think are slightly responsible for opening the developers up to the suggestion of bringing it other areas.
