If the attack power of the game king is a question mark, what should the opponent do when attacking?
If I remember correctly, the effect of aurora can only be launched in its own preparation stage, so the attack power of the other party is 0. The attack power of a card with a question mark depends on the effect of the card. Some are permanent, and some can only last for one round. For example, pterosaur attack is the sum of three sacrifices, but not when summoned from the cemetery.
