"Perfect Guards" (also known as "Perfect Defense" in the anime) are units with a special guard skill. They were first introduced in Booster Set 1: Descent of the King of Knights.
When a Perfect Guard unit is placed on (GC), by discarding one unit from its own clan, the player choose one of their units of the same clan that is being attacked, and that unit cannot be hit until the end of the battle, no matter how much power the attack has. Starting from Booster Set 16: Legion of Dragons & Blades, you no longer are required to discard one card of same clan to perform the guarding.
From G Booster Set 1: Generation Stride onward, a new variant of Perfect Guard, called Perfect Guard G, is released. Perfect Guard G can only activate its skill when called to (GC) from hand, and the player can only choose his/her vanguard for the skill. However, if the player has another copy of the card with same name in his/her Drop Zone, he/she can unflip a damage.
You may only include up to four Perfect Guard units in a deck due to their "Sentinel" ability. As Quintet Wall units also have "Sentinel", you can only use both types of unit in a deck if the total number is four or less (for example, you may use 2 Perfect Guards and 2 Quintet Walls, or 3 Perfect Guards and 1 Quintet Wall).
