the attibutes themselves are not sero, only the "current" value.

Outside of guild war, when you attack you use your ATK pts (or in war when attacking walls) or (raid bosses in raid event) and ATK points are consumed then and need to recharge. DEF points are lost when people attack you (outside of war) the game does not update the recharge value until the player logs in again then the recharge points values are displayed and adjusted. a bit of an error on the game's side,

Within war, attacking and defending does not consume either ATK or DEF pts of either the attack or the defending players, so within war you are always attacking and defending with full deck strength regardless of whether your ATK or DEF points are currently zero.
