| Active Player |
During your turn, you become the active player. If its your opponent's turn, you are the non-active player.
In the official Q&A on the Duel Masters Official Homepage, it was referred to as "that turns player", and the non-active player as "the other player". "Turn player" and "non-Turn player" were later seen.
- In the Duel Masters General Game Rules released in July 2015, it is written as "turn player" and "non turn player".
- Some results of battle can differ depending on the active player, such as the results of a battle between Death March, Reaper Puppeteer and Glenmalt, Dragon Edge.
