Because the in-game currency is always strictly limited, making the wrong upgrade choices can cripple your progression for months.
This 'jack of all trades' approach leaves you with a mediocre army that gets crushed by specialized, overleveled opponents.
Prioritizing Your Main Deck
The golden rule for free-to-play users is to identify one strong, meta-resistant deck and pour every resource into it.
Your primary goal is to get that one specific deck to maximum level so you can compete at the highest trophy ranges.
- Spells are usually the most important cards to overlevel.
- Tanks benefit massively from extra hitpoints.
- Know where you can cut corners.
The Math Behind the Upgrades
Some level differences completely alter the fundamental interactions between two specific units.
Conversely, a freeze spell's duration often remains identical regardless of level, making it a very low priority upgrade.
| Currency Type | Optimal Spending |
|---|---|
| Gold | Never buy cards from the daily shop unless absolutely necessary |
| Premium Currency | Use on global tournament bonus rewards if you get 10+ wins |
Patience is the Ultimate Weapon
Stick to the plan, support your clanmates, and carefully manage every single coin you earn.
A maxed-out free-to-play deck piloted by a highly skilled veteran is the most dangerous force in the game.
