Gods Unchained has set out a game mode that allows gamers play against cards drawn semi-randomly at the beginning of the tournament. Termed 'Seal Mode' the game is designed to reward talented players, including those who lack a large or expensive collection of cards.

Though such modes have been regular in paper card gaming, such modes have been relatively rare in online trading card games. Gamers will need to pay an entry fee. Gamers will receive a random mix of three gods to build the deck around. 60 random cards are randomly drawn from multiple sets of cards. These cards include the likes of 'Etherbots', 'Mortal Judgement', and 'Winter Wanderlands' among others.

Semi-random card pool contains cards of certain types to ensure a decent deck can be built. Each pool has at least 12 cards of 3 mana or lower. Having a pool of 60 cards, each player has to build a minimum of 30-card deck. The players build their decks out of the cards and restrained from using a card on their personal collection.

The game requires players to play a deck and play until they either lose 3 matches or win 7. The player with optima record eventually wins more rewards. For players who win 4 matches or more, cosmetic rewards are available. Each card in Gods Unchained has its own unique, non-fungible token, stored on the Ethereum layer-2 network, Immutable X.
