1) There is no special ELO
room. Most ELO
players play in Dark Corners or Danger Zone. As you probably know, they're
marked with a Pillz symbol where their stars would be. You just choose to fight one of those (or they choose to fight you).
2) I don't think you can fight non-ELO players when you're in the mode, I certainly haven't. But if you can, yes, you only get
points for ELO
3) Not really (that I've gathered
). Just play for the win, however that seems best to you. About half the decks are stacked
, so work out how to beat them, or join them.
4) When you're level 20 the toggle for ELO
mode appears in your profile (click on your name at the top of the panel to the
left). Having it on means you play in ELO
mode whenever your deck is compatible, and not in ELO
mode when it isn't.
I'll leave any advice giving to Sven, as he's probably the best ELO
player in the game!
