2 rulings from Wizards of the Coast
- 19 March 2021If there's somehow no color chosen for Paradise Plume, its middle ability can't trigger and its last ability produces no mana. The former doesn't trigger when colorless spells are cast and the latter doesn't produce colorless mana.
- 19 March 2021An ability that triggers when a player casts a spell resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
