How You Are Ranked
Most modern strategy games utilize a modified version of the Elo rating system, originally designed for professional chess.

When you go on a massive winning streak, your trophy count inflates, and the algorithm begins matching you against significantly better players.
Understand that a 50% win rate is normal.Because there are fewer Grandmasters, the algorithm struggles to find perfect matches.You will eventually stabilize. Level-Based Matchmaking
The standard Elo system works perfectly for chess because all pieces are equal, but tower rush games feature upgradeable cards.

The system will try its best to match you with someone who has the same trophies AND a similar tower level.

By artificially capping all card levels to a specific number, the algorithm can rely purely on the Elo rating.
