- You can activate Meteorain during your turn at any point from the DP to the end of your Battle Phase; you cannot activate it during the Damage Step, MP 2, your End Phase, or your opponent's turn.
- Meteorain's effect applies to all your monsters. Monsters that you Summon, Flip Summon, Special Summon, etc. after activating Meteorain still get its effect.
- When you attack with a monster that has Meteorain's bonus, and you attack a Defense Position Amazoness Swordswoman, then you will take the Battle Damage to your LP.
