The challenges gameplay mechanic is a single player mode which places the player in a number of varying environments that either add new gameplay elements or slightly change the rules of the game.

A single challenge mechanic almost always offers multiple challenges with the same mechanic, but with different AI decks. For instance, the 'Ambush' challenge mechanic offers 8 challenges, one for each of the races.

Every challenge contains 4 sets of games : one for each of the difficulty modes (easy, normal, elite, legendary). Each set has 8 decks, one for each race.

Completing a single set is done by winning at least one game against each of the 8 decks in that set. Doing so for the first time, rewards the player with an elite card. Completing an entire challenge (all 4 sets of 8 decks), will reward the player with 4 copies of the card tied to the challenge.

Below you will find the different mechanics currently available in the game. Each mechanic list the challenges it has available as well as the card that can be won from it. Click the card name for detailed info on the card. Each section also provides a 'more info' link with details about the decks that the AI uses and player submitted tactics that will help you to complete the challenge.
