The matchmaking algorithm is the unsung hero that determines exactly who you will face every time you press the 'Battle' button.

While this conspiracy theory is widespread, the reality is much more mundane and focused entirely on mathematical fairness.
Trophy and Rating Systems
Your trophy count is a numerical representation of your skill; win a match, and you take trophies from the loser.

When you go on a massive winning streak, your trophy count inflates, and the algorithm begins matching you against significantly better players.
