2 rulings from Wizards of the Coast
- 25 July 2025Although the creature you put onto the battlefield is attacking, it was never declared as an attacking creature. Abilities that trigger whenever a creature attacks won’t trigger when that creature enters attacking.
- 25 July 2025You choose the player, planeswalker, or battle the creature you put onto the battlefield is attacking. It doesn’t have to be the same player, planeswalker, or battle that the enchanted creature or any other attacking creatures are attacking.
