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

Choose a strategy that relies on common and rare cards, as these are significantly easier to request and level up.

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.
• Make your frontline unbreakable.
• 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.

Slow and Steady Progression

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.
