|“||You can't move; you can't attack; you can't even retire. All you can do is just float there.||”|
—Suiko Tatsunagi, Episode 130
When a card is affected by lock, it turns face down until the end of its owning player's turn (the card remains where it is). A unit turned face down by lock cannot be used to perform any action; it cannot attack, boost, use skills, be used to pay a cost, move to another circle or zone (including intercept) or be retired by calling another unit over it. The card is not considered a unit and the card and the circle it is on are considered to not exist for the duration of the lock skill.
In the anime, this is visually shown as two rings collapsing onto the unit reverting it into card form and on the table, the flipped down unit is shown to emit sparks when a cardfighter attempts to touch it.
All locked cards are turned face up at the beginning of the owner's end phase, this being called "Unlock" (
- Eg: If a card would leave the circle at the end of turn, it would not happen since it was locked.
Also, the card unlocked is not considered to be called to (RC) and thus on call skills are not activated.
Introduced in Booster Set 14: Brilliant Strike are units that can unlock other units before the end phase, most notably Salvation Lion, Grand Ezel Scissors who unlocks all of his rear guard units with his Limit Break. This allows units to make their opponent's locking efforts nullified or to relock units to reuse locking skills.
Q1. If I have Liberator of the Round Table, Alfred as my vanguard and 1 of my 5 rear-guards has been locked, will my vanguard's Power be 19000 or 21000 due to his Limit Break?
A1. 19000. Your locked card does not exist on the field anymore.
Q2. If my vanguard is Dragonic Overlord and my only rear-guard is an Embodiment of Armor, Bahr which is locked, will my Dragonic Overlord gets [Power]-2000?
A2. Yes. It will be treated as though there is not a unit on the rear-guard circle, meaning Dragonic Overlord will get [Power]-2000. Note that this does not affect skills such as lord, since the locked card no longer counts as a unit.
Q3. If the card text says that I may lock my own rear-guards instead of my opponent's, then do my locked rear-guards stay locked until the end of my opponent's turn?
A3. No. If you are the one who locked your rear-guards then you will turn them face up at your end phase. If you lock your opponent's rear-guards, then your opponent must wait until the end of his/her next turn. Also, be noted that Prison Gate Star-vader, Palladium's skill allows you to bypass this ruling.
Q4. If I have a locked card in one of my rear-guard circles and they no longer exist on the field can I retire it to place a new unit in it's place?
A4. No. Though the card no longer exists on the field it cannot be retired because there would be nothing to retire. The idea is that the rear-guard circle the card is locked on is engulfed by the void. So a locked card cannot be retired to play a new one.
Q5. If I unlocked my locked cards during my main phase, are they unlocked as rest or stand?
