Rulings

Official rulings from Wizards of the Coast (8).

• 2020-01-24An 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.
• 2020-01-24If an enchantment creature enters the battlefield under your control, Protean Thaumaturge’s ability can target it.
• 2020-01-24Protean Thaumaturge copies the printed values of the target creature, plus any copy effects that have been applied to it. It won’t copy counters on that creature or effects that have changed its power, toughness, types, color, or so on. Notably, it won’t copy effects that made the target creature become a creature.
• 2020-01-24If Protean Thaumaturge copies a creature that’s copying something else, it will become whatever the target is copying.
• 2020-01-24If something becomes a copy of Protean Thaumaturge, it also has the constellation ability.
• 2020-01-24Protean Thaumaturge’s ability causes it to become a copy indefinitely. It doesn’t expire during the cleanup step or if the target creature leaves the battlefield after the ability has resolved.
• 2020-01-24If an effect begins to apply to Protean Thaumaturge before it becomes a copy of another creature, that effect will continue to apply.
• 2020-01-24A 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.
