After a few matches with the Starter Decks from SiegeStorm: SiegeMode, players can construct their own deck of 34 cards using any one of the Siegestorm player faction decks.

The legion of destruction from the dark realm of Styxia is a perfect place for anyone who enjoys the salty taste of enemy tears. This faction employs many abilities that force the opponent to discard or wreak havoc on his battle lines. And since Styxian minions are expandable, you get many, many opportunities to sacrifice them for greater evil.
