The Secret World Duel has an original way of delaying the playing of cards. Each card can be covered to the delay area at the cost of this round, and played for free in the next round to achieve one card for two purposes. On the one hand, delay can make full use of the remaining costs, on the other hand, it can more easily cooperate with other cards to form various combos. In the game, there are a lot of skills to interact with delay, such as ambush, detection, resonance, etc. Each card can rely on the delay to hide its own tactical intention and take the opponent by surprise, making the battle more variable and testing the psychological game between players.

The Secret Land Duel uses the color wheel system to distinguish different forces and styles between cards. Novice summoners can simply judge the philosophy, strength and weakness of a card by its color. When players visit different worlds and places, what they can collect as cards will be classified by the "color wheel". The five basic colors are white, blue, black, red and green. Each creature, artifact, magic, group, force and country can be classified into one or more of them. Each color in the color wheel represents some specific personality.

Rotating play is an innovative play method under the competition mode of "Secret Arena Duel". Compared with the common ladder mode and the open arena play method, the round play method tests the overall strategy of players and their familiarity with each card. The rules of rotation play are relatively complex, but there is a fascinating depth of skills to explore. This article will explain the basic rules of round robin, and help summoners understand the operation of round robin more quickly.

The open play method of Secret Arena Duel has great innovation on the basis of the arena mode. In the arena mode of most card games, players will use this set of cards to fight until the end after selecting a good set of cards from a random library. The Secret Land Duel innovatively provides a randomly generated open play library, which has 75 cards, and players can return to the library to rebuild their own card sets after each game.

The active skills of the creature card in Secret Region Duel can be roughly divided into two categories, one is the action skill (that is, you can use this skill only when the creature is not acting, and the creature will be deemed to have attacked and cannot act again after using it). The other is additive (this skill only deducts the crystal points that need to be paid, and the creature can still attack after use). The active skills of cards in the game are various and changeable. They may be the finishing touch to improve the quality of a single card, and may be the tactical core of building a deck. How to use these active skills well is a required course for all summoners
