I actually remember playing the Proving grounds B tourney.
Good Times!
Can I get another shot?

I'd like to play.

Sign me up if there's room.

If it is still possible, I would like to join as well.

If I understand well, I will have to play 2vs2 and 3vs3 games, not only 1vs1.
If it is true, then thank you very much in advance for my partners to teach me what are the specificities of these game types (I have played only 1vs1 games till now) :)
