Star-vader, Chaos Breaker Dragon

"Lock" (呪縛ロック Rokku) is a keyword, which refers to the action to change the state of a rear-guard to be a locked card, and introduced in Trial Deck 11: Star-vader Invasion.

In the anime, Lock is visually shown as two black rings collapsing onto the unit reverting it into card form and on the table, the face down card is shown to emit sparks when the player attempts to touch it, and at the end of the turn, all cards that were affected return to be face up automatically without making a turn.

In Cardfight!! Vanguard G, Lock is shown as a red sphere engulfing the locked unit on the field. However, the Star-vaders' variation continue with two orbiting black rings around the lock.

How it Works

When a rear-guard is locked, it turns face down and remains face down where it is until the end of its owner's turn. A locked card loses all characteristics present on its face-up side, as well as other characteristics that it received before being locked. A locked card is not a rear-guard (and hence it is not a unit either), and both it and its circle are considered to not exist while it is locked. A locked card has no standing or resting state by game mechanic, but physically, the player is free to choose the orientation to place their locked cards (being vertically the most common).

Since a locked card is not a unit, it cannot be used to perform any action; cannot attack, boost, intercept, use abilities, be used to pay costs, be moved to another circle or zone, or be retired by calling another unit over it. A locked can only be used by effects that explicitly affect a locked card.


When a locked card will be turned face up, the action is known as "unlock" (解呪アンロック Anrokku). Said action means "turn the locked card face up in [Stand] state", which normally occurs at the beginning of the owner's end phase after it was locked. An locked card that is unlocked returns to be a rear-guard along the circle where it is. However, the unlocked card is considered to be a different card than the original, and therefore, all effects received to that card before it was locked disappear (For example, if the unit had to leave the field at the end of turn, this does not happen since it was locked). Also, the unlocked card is not considered to be placed on (RC), and so "placed on" effects are not activated.

Starting from Booster Set 14: Brilliant Strike, there are cards that can unlock with their effects, most notably Salvation Lion, Grand Ezel Scissors, who can unlock all of your locked cards with his Limit Break. This allows units to make their opponent's locking efforts nullified or to relock units to reuse locking abilities. G Trial Deck 5: Fateful Star Messiah introduces the first cards whose effects are achieved when they are unlocked.

Omega Lock

"Omega Lock" (Ω呪縛オメガロック Omega Rokku) is a special variation of lock introduced in Booster Set 15: Infinite Rebirth.

When a locked card is affected by Omega Lock, during the owner's next turn, on his/her end phase, they cannot unlock that card. Said locked card will only be unlocked during the owner's next end phase after it is affected. However, locked cards affected by Omega Lock still can be unlocked normally or with effects during any phase in any turn, excluding the "next end phase" where they cannot be unlocked by anything.

If a locked card is affected by Omega Lock multiple times in the same turn, it will not prolong the Omega Lock's duration of two turns.
