Trigger

Lozenge Magus is a [Heal] trigger unit

"Trigger" (トリガー Torigā) is the defining characteristic of trigger units. Trigger units are a type of unit with a yellow card frame, and are all grade 0 (with the exception of one card, which is not tournament-legal). Each trigger unit has a trigger icon located at the top right of the card. During deck construction, a deck must contain exactly 16 trigger units, with a maximum of four heal triggers (even if they have different card names).

How it Works

• A trigger effect activates while it is in the trigger zone after being revealed for a trigger check. A trigger check is performed by putting the top card of the player's deck into his or her trigger zone, and if that card has a trigger effect, it activates immediately. After resolving all effects activated, regardless of whether the card has a trigger effect or not, if the card is still in the trigger zone, it is immediately moved to another zone depending on the type of trigger check:
  • Damage Check: Put the card face up into your damage zone.
  • Drive Check: Put the card into your hand (this is not considered "drawing a card").
• When a player must check for multiple triggers at once, perform each trigger check separately before revealing the card for the next check. For example, if a player must perform two trigger checks and his first trigger check reveals a draw trigger, the player will draw one card before performing the second trigger check.
• To activate a trigger effect, the player must have at least one vanguard or rear-guard with the same clan as the trigger unit. However, the trigger effect does not have to be applied to a unit of the same clan as the trigger unit. (This rule is no longer necessary, due to Clan Fight regulations only allowing one clan per deck.)
• Trigger effects must always be activated if possible. Therefore, if a heal trigger is activated, you must heal one damage if you fulfilled the condition, even if it causes an effect to disappear, such as a [CONT] Limit Break.

Examples

(These examples are no longer relevant, due to Clan Fight regulations only allowing one clan per deck.)

• If "Battleraizer" is revealed and the player has one or more "Nova Grappler" units present, the trigger effect activates.
• If "Grim Reaper" is revealed by "Alfred Early" and the player has "Blaster Dark" as a rear-guard, the trigger effect activates since a Shadow Paladin unit is present.
• If "Dragon Monk, Genjo" is revealed by "Mr. Invincible", but the player does not have any Kagero rear-guard present, the trigger effect cannot be activated as a result.

Trigger Effects

All triggers grant a [Power] increase effect as noted on their trigger icon (+5000 or +10000), which lasts until the end of the turn, as well as another effect specifc to the trigger type. These are considered separate effects, so the [Power] increase and the trigger's effect can be applied to two different units if the player wants to, and in any order the player wants.

• "Critical Trigger" /: The player chooses one of his/her units and gives it [Critical]+1 until the end of that turn. It is noted by the color yellow.
• "Draw Trigger" /: The player draws a card. It is noted by the color red.
• "Front Trigger" : Instead of the player choosing a unit, all of the units in the player's front row receive the [Power] increase. It is noted by the color pink. This trigger type was introduced with  Series.
• "Heal Trigger" /: If the player has equal or more damage than his/her opponent, the player chooses a card from his/her damage zone and puts it into his/her drop zone (this action is called "heal"). It is noted by the color green.
• "Stand Trigger" : The player chooses one of his/her units, and if it is a rear-guard, changes it from rest to stand . It is noted by the color blue. This trigger type was retired with the introduction of Series.

Icons Within Card Texts

In card text and some official explanations, trigger effects are referred to with the following icons. Each icon is the kanji of the trigger's name, except for the critical trigger, which is represented by the [Critical] symbol.

In Cardfight!! Vanguard ZERO

As there are no grade 0 cards in Cardfight!! Vanguard ZERO except first vanguards, trigger effects are instead assigned to grade 3 cards. During deck construction, the player may decide what trigger icons they want for their cards. When a drive check reveals a trigger effect, that card is put into the drop zone instead of their hand after resolving its effects. Additionally, when a trigger is activated during a damage check the [Power] is automatically given to the Vanguard.

Frequently Asked Question

1. Question: If I reveal a heal trigger for a damage check while I have one damage and my opponent has two damage, can I heal?
   Answer: No, since the heal trigger is in your trigger zone while its effect is being resolved.
2. Question: If an effect causes a card to be put into a player's damage zone, is it a damage check?
   Answer: Unless otherwise specified in that effect, it is not a damage check.

Trivia

• With the introduction of Booster Set 11: Seal Dragons Unleashed, there are triggers that you can have up to sixteen copies in a deck, bypassing the usual rule of up to four copies in the deck. Currently, the only cards than can do this are Mass Production Sailor and Machining Cicada.
• In the Cardfight!! Vanguard Anime Season 1, Episode 2, It is shown that Aichi's Yggdrasil Maiden, Elaine has 6000 [Power]. This was either an accident, or Bushiroad was still considering at that moment whether a trigger should have the same power as normal Grade 0 units. It is also possible that the mistake was intentional, as Elaine's boost would allow Gallatin to reach 16000 [Power], enough to force a 10000 [Shield] by Kai when Dragonic Overlord was attacked.
• Starting with Booster Set 6: Breaker of Limits, every booster pack comes with one trigger unit per pack. This does not apply to Extra Boosters.
• In the manga, when the card revealed by a check is not a trigger, it is called "blank trigger".
