Shadowverse is a digital card battle game by Cygames with some connection to the Cygames fantasy world. The game is divided into a story campaign spread across multiple worlds sci-fi or fantasy alike and a PVP mode featuring various tournaments in addition to "tie-in" events (collaboration events) between different franchises.
To begin, one must choose one of eight classes to play with (whichever one you choose can be changed later) each with a different playstyle and mechanics. Each class has access to a personal selection of cards in addition to a general pool (which is counted as a ninth class not playable on its own).
Each player can mulligan their starting hand to find better cards in case of a bad draw. The player who goes first gets 2 evolution points, and the player who goes second gets 3 evolution points.
At the start of their turn, each player draws one card from their deck and places it in their hand. The player who goes second draws two cards on the first turn. Cards in the deck can't be seen during battle.
Shadowverse was released in June 2016. An anime adaptation by Zexcs aired from April 2020 to March 2021. A second anime series titled Shadowverse Flame is currently being aired following the events of the first one after a three-year time skip.
