sageoflogic replied to your post: Say Withengar Unbound dies and it has undying would I be correct in assuming it doesn’t come back since when it enters the graveyard it isn’t a creature anymore since it flips back to elbrus?
So +1/+1 counters could legally be attached to it as an artifact?
You could put +1/+1 counters on any permanent, really. It only increases power and toughness if it has them as a value (Gideon Jura, Man-lands, etc) though.
