Card Mechanics

These are different Card Mechanics, effects and skills that a unit may have or use in a battle.

Ranks
Similar to Cardfight! Vanguard! has Grades and Weiss Scharz has Levels, ZeoXros!! Warframe!! has Ranks. Each Ranks has separate into tiers.
 * "Low-Rank Tiers" consist of units that are Rank 1, 2, and 3. They're known to be weaker units but give good support. Low-Ranks has 3000 - 7000 Power, 10000 Shield, and have the "Boost" ability.
 * Mid-Rank Tiers consist of units that are Rank 4, 5, 6. They're very strong units for well-balance. Mid-Ranks has 6000 - 12000 Power, 5000 Shield, and have the "Intercept" ability.
 * High-Rank Tiers consist of units that are Rank 7, 8, 9, and 10. They're very powerful however, it will take very long to call them unless you Rank-Up faster with a "Rank-Up Trigger". High-Ranks has 10000 - 20000, No Shield, and have the "Twin Trigger" ability.

Skill Icons
Very similar to the Skill Icons in Cardfight, they are common abilities that nearly all units have based on their Ranks. Each icon shows which ability the unit has.

Boost

 * When your unit declares its attack, you can [Rest] a unit with "Boost" in the Assist Zone of the same column as the attacking unit to have it boost the attacking unit. The power of the boosted unit increases by the power of the boosting unit.
 * The power of the boosting unit is continuously added to the boosted unit for the duration of the battle. If the boosting unit gains power, the gained power is added to the boosted unit. If the boosting unit ceases to exist, the boosted power is lost.
 * Currently used by Low-Rank units.

Intercept

 * During your opponent's guard step, if your rear-guard with "Intercept" is in the Front Zone, is not being attacked, and another of your units is being attacked, you can move the card with "Intercept" to your Guard Zone.
 * Currently used by Mid-Rank units.

Twin Trigger

 * It gives the unit with "Twin Check!!" drive+1, allowing them to drive check two cards instead of one during the trigger step.
 * Currently used by High-Rank units.
