- Windstorm: X - (When Attacks) When this spirit is blocked, your opponent exhausts the specified number of spirits they control.
This ability allows Green to exhaust many spirits, clearing the opponent's field of blockers in a few attacks. Examples of cards with this ability include The Providence Hououga and The BladeKingBeast Byak-Garo.
