The Battle Damage doubled by “Stone Statue of the Aztecs”’ effect is still considered Battle Damage (not effect damage).
If “Rod of the Mind’s Eye” is equipped to “Stone Statue of the Aztecs”, the Battle Damage will be 1000.
The Battle Damage is doubled during damage calculation.
When “Amazoness Swordswoman” (1500 ATK) attacks “Stone Statue of the Aztecs” (2000 DEF), the controller of Stone Statue of the Aztecs takes 1000 Battle Damage.
