Spells without targets and protection

[dber]

I would like to know, if I have a card like mother of runes in play, and an opponent throws a wrath of god or zealous persecution or firespout, cards that have no target, if I tap my mother of runes if it would be destroyed. Thank you

Protection from (color) would prevent damage from nontargeted spells, but board wipes like Wrath of God would still kill it.

Definition of protection in mtg is can not be targeted, blocked  dealt damage or enchanted by whatever the protect is ie color or colorless or artifacts ect. Board wipes like day of judgment will destroy everything that is not indestructible.

Based on what the card says to be destroyed, wrath of gods says destroy all creatures they can not be regenerated, so unless ur creatures have indestructible it wipes them off the board. Even if ur creature has protection from white and has shroud or hexproof does not matter. Which again definitions of shroud and hexproof are can not be the target of spells or just spells ur opponent's control

[RuthlessRut]

Same goes for spells that say "each" instead of target like the overload cards and cards like polymorphist jest, protection, shroud, and hexproof will not stop those spells

I like to remember the word "target". If a spell doesn't have the word "target" in it then it usually bypasses hexproof, shroud, protection.

A good way to remember it is the acronym "DEBT"  Something with Protection cannot be:
Damaged by whatever it has protection from (color, spells, converted mana cost of 3 or less)
Enchanted by whatever it has protection from (color, etc)
Blocked by whatever it has protection from
Targeted by whatever it has protection from. 

A lot of people forget the enchanted part.  If a creature has protection from a color, then it can't receive enchants of that color.  This also means that if you give it protection from a color, all enchants on the creature of that color fall off.
