Rulings
- Drawing a card is not optional. You must draw 1 card any time Airknight Parshath inflicts Battle Damage to the opponent’s LP. This includes direct attacks, and when it battles with a monster with a lower ATK/DEF.
- If the opponent activates Waboku or Kuriboh to reduce the Battle Damage to 0, you do not draw.
- When Airknight Parshath attacks a face-down monster with a Flip Effect and inflicts Battle Damage, you draw 1 card before the Flip Effect is applied.
