6 rulings from Wizards of the Coast
- 1 March 2010As the ability resolves, you can't put the Ogre token onto the battlefield without explicitly giving the attacking player the option to pay {3}, even if the attacking player has forgotten about this ability.
- 1 March 2010If you're the defending player, Kazuul's ability triggers once for each creature that attacks, not just once per combat. The attacking player chooses whether to pay {3} or let you have an Ogre token each time one of those abilities resolves.
- 1 March 2010In a multiplayer game, the ability checks whether you're the defending player for each individual attacking creature. For example, if one creature attacks you and two creatures attack another player, Kazuul's ability triggers just once.
- 1 March 2010If an attacking creature has a "Whenever this creature attacks" ability, that ability is put on the stack first, then Kazuul's ability is put on the stack. Although Kazuul's ability will resolve first, and potentially create an Ogre token, any target of the other ability will already have been chosen at this point, and thus could not have been the new Ogre token.
- 1 March 2010The ability triggers and resolves during the declare attackers step. If you put an Ogre token onto the battlefield as a result, you may block with it during that combat phase.
- 28 July 2023You're the defending player if a creature is attacking you, a planeswalker you control, or a battle you protect.
