As the tittle says, beside the raffle tickets gods unchained will be giving genesis card packs for competitive wins, this was posted for one of the admin in the game discord today, the offer will last just this weekend (for about 3 days), so if you are a GU players its better to give a shop for some free extras genesis cards.
