Domri vs. Master of Waves

[Mattao19]

Can I -2 {Domri Rade} and target {Master of Waves} I don't know how protection works vs. PW

[Riskiersquirrel]

As long as your target creature isn't red you should be fine

[Mattao19]

But Domri is Red and Master has pro Red so can Domri legally target {Master of Waves}?

[Avnger345]

I'd say no then

[Mattao19]

Thank you!

*Taken from the FAQ section*
This ability is written as Protection from (quality). A creature with protection from a quality cannot be enchanted, equipped, blocked, or targeted by anything with that quality, and all damage that would be dealt by a source of that quality is prevented, barring exceptions which explicitly state otherwise. For example, a creature with protection from red cannot be enchanted by red Auras, blocked by red creatures, targeted by red spells and abilities, or take damage from red sources. A common mnemonic for which effects are prevented by protection is the acronym DEBT, standing for "Damage, Enchant (or Equip), Block, Target". Note that the protection ability does not prevent effects that do not target. For example, though Black Knight has protection from white, it would still be destroyed by Wrath of God since Wrath of God does not target a creature.

If a creature gains protection while some of these effects are present, different things may happen. Any Aura, Equipment, or Fortifications attached to it that are no longer legally attached to it "fall off", becoming unattached (for example, a creature with a red Aura gains protection from red or a creature with an Equipment attached gains protection from artifacts). Auras that are not attached to anything are then put into their owners' graveyards, while Equipment and Fortifications stay on the battlefield. Any spells of that quality (or abilities of permanents of that quality) that target it lose that creature as a target (for example, a creature gained protection from red in response to being targeted with Lightning Bolt). If they no longer have any legal targets, the spell "fizzles" and is countered by the game rules. However, a creature gaining protection in response to being blocked by a creature does not cause it to become unblocked, though it will prevent all damage that blocking creature would do to the creature with protection.

Initially this ability was limited to "Protection from (color)," but was later expanded to allow "Protection from artifacts" in Urza's Legacy, and officially expanded to allow "Protection from (quality)" in Invasion with the printing of Shoreline Raider. In Conflux, a card called Progenitus has "Protection from everything" -- meaning it cannot be blocked, cannot be equipped or enchanted, cannot be targeted by spells or abilities, and cannot be dealt damage. Most cards with protection are either white or an an enemy color from the color of protection offered (i.e. most cards with protection from blue are blue's enemies of red and green).

From the Comprehensive Rules:

    702.16. Protection
        702.16a Protection is a static ability, written "Protection from [quality]." This quality is usually a color (as in "protection from black") but can be any characteristic value. If the quality happens to be a card name, it is treated as such only if the protection ability specifies that the quality is a name. If the quality is a card type, subtype, or supertype, the ability applies to sources that are permanents with that card type, subtype, or supertype and to any sources not on the battlefield that are of that card type, subtype, or supertype. This is an exception to rule 109.2.
        702.16b A permanent or player with protection can't be targeted by spells with the stated quality and can't be targeted by abilities from a source with the stated quality.
        702.16c A permanent or player with protection can't be enchanted by Auras that have the stated quality. Such Auras attached to the permanent or player with protection will be put into their owners' graveyards as a state-based action. (See rule 704, "State-Based Actions.")
        702.16d A permanent with protection can't be equipped by Equipment that have the stated quality or fortified by Fortifications that have the stated quality. Such Equipment or Fortifications become unattached from that permanent as a state-based action, but remain on the battlefield. (See rule 704, "State-Based Actions.")
        702.15e Any damage that would be dealt by sources that have the stated quality to a permanent or player with protection is prevented.
        702.16f Attacking creatures with protection can't be blocked by creatures that have the stated quality.
        702.16g "Protection from [quality A] and from [quality B]" is shorthand for "protection from [quality A]" and "protection from [quality B]"; it behaves as two separate protection abilities. If an effect causes an object with such an ability to lose protection from [quality A], for example, that object would still have protection from [quality B].
        702.16h "Protection from all [characteristic]" is shorthand for "protection from [quality A]," "protection from [quality B]," and so on for each possible quality the listed characteristic could have; it behaves as multiple separate protection abilities. If an effect causes an object with such an ability to lose protection from [quality A], for example, that object would still have protection from [quality B], [quality C], and so on.
        702.16i "Protection from everything" is a variant of the protection ability. A permanent with protection from everything has protection from each object regardless of that object's characteristic values. Such a permanent can't be targeted by spells or abilities, enchanted by Auras, equipped by Equipment, fortified by Fortifications, or blocked by creatures, and all damage that would be dealt to it is prevented.
        702.16j Multiple instances of protection from the same quality on the same permanent or player are redundant.

a creature with protection from red cannot be enchanted by red Auras, blocked by red creatures, targeted by red spells and abilities

Thank you for... Not answering he question...

Actually, he did


This ability is written as Protection from (quality). A creature with protection from a quality cannot be enchanted, equipped, blocked, or targeted by anything with that quality,

Domri is the source doing the targeting, so you cannot use him to fight the master.

Short answer: this.
