3 rulings from Wizards of the Coast
- 24 January 2020If an enchantment creature enters the battlefield under your control, Pious Wayfarer’s ability can target it.
- 24 January 2020A constellation ability triggers whenever an enchantment enters the battlefield under your control for any reason. Enchantments with other card types, such as enchantment creatures, will also cause constellation abilities to trigger.
- 24 January 2020An Aura spell that has an illegal target when it tries to resolve doesn’t resolve and is instead put into its owner’s graveyard. It doesn’t enter the battlefield, so constellation abilities don’t trigger.
