Blue

Blue (青 Ao) is one of the seven Colours in the Digimon Card Game. It was first introduced in ST-2: Starter Deck Cocytus Blue as one of the first three Colours in the game.
==Themes==
Blue is notable for containing many cards associated with the secondary protagonists of the various Digimon anime series, such as their partner Digimon or the characters themselves as Tamer cards. The Digimon cards found in Blue are often Digimon based on mammals like canines or canids, as well as marine or water-based Digimon. Common Types found in Blue Digimon include Beastkin or Sea Beast.
==Mechanics==
Blue is a Colour focused on both control and combo-making, containing effects that reduce the opponent's options of counter-play. Blue cards are often capable of hindering the opponent's game plan by removing the opponent's access to Inherited Effects, as well as making attacks that are difficult to counter by utilizing unsuspending effects to attack multiple times and to negate battles with Security Digimon. In addition, Blue cards often possess effects to return opposing Digimon to the hand, removing them from the field while bypassing abilities. Common keywords in Blue include .
====Discarding Digivolution Cards====
One of Blue's core mechanics revolve around discarding digivolution Cards from opposing Digimon. Cards like and contain effects that trash the digivolution cards under the opponent's Digimon, thus being able to hinder the game plan of decks with a heavy focus on Inherited Effects or effects like that rely on the possession of digivolution cards. To complement these effects, many cards, such as or , grant bonuses if the opponent controls Digimon with no digivolution cards, and some cards like have devastating effects that specifically target Digimon lacking digivolution cards. It can be noted that these cards also offer an advantage against Digimon that are directly played to the field, as those cards would not have digivolution cards to begin with.
====Combo-based Attacking Capabilities====
In addition, many Blue decks contain Digimon that are capable of making attacks that are difficult to counter against. As seen in or , these Digimon contain effects that unsuspend themselves during its owner's turn, allowing them to either make more attacks or to remain unsuspended and prevent itself from being attacked the next turn. In addition, while many Red Digimon see a weakness in simply having its attack be stopped by opposing Digimon, Blue's ability to make multiple attacks makes it difficult to stop even in the face of blockers.
Aside from unsuspension effects, Blue also sees a variety of Digimon containing , preventing the Digimon from being destroyed in a battle with Security Digimon. This allows it to bypass one of the usual risks of making a Security Attack, and forces the opponent to counter by either blocking with a Digimon with a higher DP or to attack it after it has been unsuspended. Particularly notable examples of in Blue include and . The former is able to reduce the risks of attacking even further by being capable of preventing itself from being targeted with attacks, while the latter is able to combine with unsuspending effects found on itself and to make multiple attacks without carrying the risk of being destroyed by a Security Digimon.
====Hand Bouncing Removal====
Blue also contains removal cards in the form of returning opposing Digimon to the opponent's hand, and discarding its digivolution cards in the process. Although limited to targets below a certain level threshold, cards like containing these effects offer a competent way to remove opposing threats while bypassing the commonly found effects. In addition, cards like take advantage of this mechanic by increasing the number of cards in the opponent's hand through returning their Digimon to their hand, and granting bonuses based on this number.
