While upgrading individual unit cards is the primary focus of combat, managing your overarching account level is equally critical.
Therefore, understanding exactly how to efficiently generate account experience points (XP) is vital for long-term survival on the ladder.
The Primary Source: Upgrading Cards
However, the ratio of gold spent to experience gained changes drastically depending on the level of the upgrade.
If your sole goal is to level up your king tower quickly, upgrading all of your low-level cards evenly is the most cost-effective method.
- Upgrade your main deck first, always.
- The cost is microscopic, but the XP bump is significant.
- You will run out of gold and cripple your main deck.

|---|---|
