Why can a Mirran crusader be killed by black sun zenith even though he has protection from black and green?
Protection from a color protects from "targeting" and damage from spells. If a card uses a the word "target" then it can't touch him but {black suns zenith} gives ALL creatures -1/1 counters, thus bypassing the word "target". Works the same that a pro white creature could be killed by {day of judgement}. Also important to note that a pro red creature could not be killed by {pyroclasm} since protection does prevent damage. Capice 👌
Exactly!
I always use DEBT to remember what protection does:
D - Damage is prevented
E - Equip/Enchanting is prevented. (e.g. a pro-black creature can't be equipped or enchanted by black permanents)
B - Blocking is prevented
T - Targetting is prevented.
So a black creature can't block a {Mirran Crusader}? Or can it block but not give any damage to the crusader. Everytime I play my {Mirran Crusader} my opponents block and not give any damage. What is the correct path
Black creatures cannot block pro-blacks.
