He’s unscarred cause he dies after taking any hit before it has a chance to scar up

For the protection clause, is it EVERY mana cost other than the one selected on ETB, or just the other 2 of 3 listed? Like will this always have protection against 1 CMC and 5(+) CMC?

The Rules Manager also said that if there is no chosen number for any reason, it does not have any protection at all because the abilities are linked.

706.7a If an ability causes a player to “choose a [value]” and a second, linked ability refers to that choice, the second ability is the only ability that can refer to that choice. An object doesn’t “remember” that choice and use it for other abilities it may copy later. If an object copies an ability that refers to a choice, but either (a) doesn’t copy that ability’s linked ability or (b) does copy the linked ability but no choice is made for it, then the choice is considered to be “undefined.” If an ability refers to an undefined choice, that part of the ability won’t do anything.

Or, on a standard d6, assign each of the numbers 1,5, and 6 to one of the target values. Then you only need to roll once.
