Runed Halo says:
Runed Halo WW
Enchantment
As Runed Halo enters the battlefield, name a card.
You have protection from the chosen name. (You can't be targeted, dealt damage, or enchanted by anything with that name.)
Can I name PROGENITUS, who has protection from everything, so that I get protection from progenius?
or in other words, does the protection from everything progenitus has also protects it from being named as the card for Runed Halo?
