If simply collecting cards is getting a little dull and repetitive, you'll want to start redeeming these Anime Card Battle X codes instead. On top of free packs with potentially boosted rare rates, these codes might just increase the power of an already stellar staple in your deck. Anime Card Battle X is a reminder that most card games aren't just for stuffing into a binder to hopefully sell on for a tidy profit later down the line: they're deep, complex strategy games designed to test the brains of two opposing players. And while this one lets you duke it out against NPCs from across various anime franchises, you can challenge other players, too.
