Life Burst (ライフバースト Raifu Bāsuto) is an ability type found on SIGNI and spells, located under the rest of their abilities. A card's Life Burst ability is triggered whenever it is crushed as a life cloth and sent to the check zone. After the Life Burst ability is used, the card is sent to the ener zone. Life Burst abilities can be used regardless of the card's limiting condition.
Using a Life Burst ability is optional.
