"Skill icons" (スキルアイコン Sukiru Aikon) are common abilities that many cards have. Each icon shows which ability the card has.
Cards can gain or lose skill icons through the use of other abilities. As skill icons are not inherently tied to a card's grade, abilities that alter the grade of a card will not affect its skill icon.
- If your unit attacks in a battle phase, you can [Rest] a unit with "Boost" in the back circle of the same column as the attacking unit to make it boost the attacking unit. The power of the boosted unit increases by the power of the boosting unit.
- If your vanguard is in Legion, you choose one of the two vanguards to be boosted.
- The power of the boosting unit will continuously added to the boosted unit. If the boosting unit gains power, the gained power will be added to the boosted unit. If the boosting unit ceased to exist, the boost power is lost.
- "Boost" only last until end of a battle.
- Currently only grade 1 and grade 0 cards have "Boost".
- During your opponent’s guard step, if your unit with "Intercept" is in a front rear-guard circle, is not being attacked, and another of your units is being attacked, then you can move the card with "Intercept" to your guardian circle.
- This is considered moving the unit from rear-guard circle to guardian circle, thus "When this unit is placed on (GC)..." abilities does not activate.
- The units are treated as guardians in the guardian circle, and will retire once the battle ends.
- Currently only grade 2 cards have "Intercept".
- A Drive ability. "Twin Drive!!" gives the unit with the ability +1 drive, allowing them to drive check two cards instead of one during the drive step.
- Currently only grade 3 and grade 4 normal unit have "Twin Drive!!".
- A Drive ability. "Triple Drive!!" gives the unit with the ability +2 drive, allowing them to drive check three cards instead of one during the drive step.
- Currently only grade 4 G Units have "Triple Drive!!!".
- Only G guardians lack a skill icon.
- In the anime, skills that gains [Shield] upon intercepting is called "Especial Intercept".
