What does hate do?

It's highly dubious how happy I would be to have the Rune over the body. The mandatory sacrifice seems like an aspect that is weirdly preventing me from attacking with this viking.

Hate was a typo. I was going for the elemental with haste and dies at the end of the turn thing that red gets. I thought that if it didn't get bodied by a creature (and presumably die with its 1 toughness), you could get a red rune.

I think gaining a Rune is alright, but right now the "Sacrifice this at end of turn"-part is missing, which means this easily could stick around as a defensive creature (3 power can trade with some sizable threats and discourage them from attacking).

How about: "At the beginning of your end step, sacrifice ~. Then if ~ has dealt damage to an opponent this turn, carve a red Rune." That way it's actually some sort of Arc Runner. Actually, you wouldn'T need the if-clause:

> "At the beginning of your end step, sacrifice ~ and carve a red Rune."

I actually think it would be even better the other way around: A red Rune could easily serve as post-combat removal of a creature that has been dealt nonlethal damage blocking Cleavespell Viking. That would lead to less common-friendly wording though... But I'd still suggest the above option.
