The vast majority of mobile arena battlers utilize a 'freemium' monetization model: the game is free to download, but upgrading your units requires massive amounts of in-game currency.
Every single gold coin and green gem must be managed with the precision of a corporate accountant.
Why Gold is King
While premium gems seem like the most valuable currency, veteran players know that standard Gold is the true, brutal bottleneck of progression.
If you switch decks constantly and try to level up thirty different cards, you will end up with thirty mediocre, mid-level cards that are completely useless against maxed opponents.

The Smart Use of Premium Currency
As a free player, you will slowly accumulate a small stash of premium gems from daily chests and achievements.
You are essentially betting your gems on your own mechanical skill, converting premium currency into massive piles of gold and cards.
