Ranks

Win Ranked Battles to gain trophies and climb the ranks - losses take a few away. The higher your rank, the fewer trophies a win gives.

Shields
Right after you rank up you get a few shields, so a loss or two won't drop you straight back down.
Seasons
A season lasts about a month. At the end you get a reward for the highest rank you reached.
Season reset
Below Champion you keep your trophies. Champion and Legend players drop one division when a new season starts.
Trophy Ladder
Separate rewards for your best trophy count ever. It never resets, so each reward is yours to claim once.
