Well, "die" and "be sent to the graveyard" mean exactly the same thing in Magic-ese, so you can remove the second one and have functionally identical text.

Name and effect makes me think a little more white than black, but color-wise this is fine.

Rare seems too much, more common.

Yeah, that first line was redundant. This is semi-relevant and helps prevent confusion because there are a few cards in this set that exile killed creatures instead of graveyarding them. Common seems really good for this. Notably, these creatures get to use on death effects and ETB effects a second time, which is an upgrade over indestructible. Moving to uncommon for now
