1 official ruling from Bandai, last ruled Jan 24, 2025. Straight answers to how this card actually resolves.

I have two copies of this card in my Battle Area. At the End of Your Turn, I attacked with the first card's [End of Your Turn] effect. Can I attack with the second card's [End of Your Turn] effect after that?
No, you cannot attack with the effect of the second card. While attacking, you cannot declare a new attack. In this situation, at the end of your Turn, the two [When End of Your Turn] effects of this card are triggered simultaneously, and you attack with the first [End of Your Turn] effect. Before the Counter timing, the second [When End of Your Turn] effect can be activated, but since you cannot declare an Attack during the Attack, the second card cannot attack even if you activate it.
