- 27 April 2018If Warcry Phoenix enters the battlefield attacking, it wasn't declared as an attacking creature that turn. Abilities that trigger when a creature attacks won't trigger.
- 27 April 2018As Warcry Phoenix returns to the battlefield because of its triggered ability, you choose which opponent or opposing planeswalker it's attacking. It doesn't have to attack the same opponent or opposing planeswalker as your other attacking creatures.
