Anime Card Battle X has a small active code pool right now. The current codes focus on weather rerolls and potion boosts, so they are worth redeeming as soon as you load into the game.

Redeem Anime Card Battle X codes
Step 1: Open Anime Card Battle X on Roblox. You can redeem codes as soon as you enter the experience.
Step 2: Click the Codes button on the left side of the screen. This opens the code entry field.
Step 3: Enter one of the active codes exactly as written. Then press Redeem.
Step 4: Watch for the reward to appear at the top of the screen. That on-screen reward display is the sign that the code was accepted.
The current rewards are built around better rolls and more rerolls, which makes them useful whether you are chasing stronger cards or trying to work through new content faster. The Roblox game page also points players toward free codes, so after you claim the active set, the same in-game Codes menu is where you will redeem any later additions.
