I needed to edit my review because the monetization has gotten absurd. All the banners for the past few months and the foreseeable future are limited units. They've decreased the amount of currency you get both as a free player and by paying. The upcoming changes for the anniversary make the game even more p2w and jncrease the grind even further. You need 36k premium currency just to guarantee a card not even an actual unit. Stay away and play something else.
