I play Doubles and Solo Standard. Solo Standard is for players that aren't in a party, but still play 3v3. Means you're not getting matched against a team of players, which makes it a bit better. Also, your overall rank is different from your rank for each match type. Your opverall rank only goes up, but your rank for each match type can go up and down as you win/lose game.s So if you continually suck, you'll drop to lower divisions and matchup more correctly.
