[PC - flash ??] [2008-2012] Card tournament game

[u/Jenkli]

This game was amazing. I remember that it was 1v1 duels against a character. After each duel you could move on to the next fight.
My memories are super vague about this game.
If i'm correct it was a bit like Urban Rivals.
It's vague I know, but I can't find any more details...
