Understanding exactly which cards to prioritize is the key to climbing the ladder without spending real-world money.
Many new players make the fatal error of trying to keep every single card in their collection at the same level.

Focusing on a Single Win Condition
Avoid decks that require four or five legendary cards, as maxing them out will take literally years of grinding.
Once you have chosen your primary deck, do not deviate from it, no matter how tempting a new card release might seem.
- Spells are usually the most important cards to overlevel.
- Make your frontline unbreakable.
- Know where you can cut corners.
The Math Behind the Upgrades
For example, if your spell is one level lower than an enemy's swarm, it might fail to kill them instantly.
If your primary removal spell cannot kill the most popular meta unit, it must be upgraded immediately.
| Currency Type | Optimal Spending |
|---|
| Gold | Save strictly for upgrading cards in your main deck from level 13 to 14 |
| Diamonds | Use on global tournament bonus rewards if you get 10+ wins |
Playing the Long Game
It is incredibly tempting to upgrade that shiny new legendary card, but it will only slow down your overall ladder progress.
A maxed-out free-to-play deck piloted by a highly skilled veteran is the most dangerous force in the game.
