Challenges are special events with unique rules and rewards. They range from Classic Challenges (standard rules, small entry fee) to Grand Challenges (higher entry, better rewards) and special Event Challenges (often free entry, unique rules, and exclusive rewards like Emotes or Tower Skins). Participating in challenges is an excellent way to test new decks, practice under pressure, and earn significant Gold and cards. Always check the rules before entering, as they can drastically alter gameplay.
