Actually the fastest way to get points is Supernatural yut, gives more points than one card and unlike legends
u don't get paired with retards that make u lose and get a little amount of points

basic key settings ftw

legends return is the fastest if you win
otherwise ya one card

I tried that, but since I don't use standard key settings it felt incredibly awkward... and I died a lot.

Battle of the Legends is also a nice game to play if you don't mind spending a bit more time for more points.
