Undying lands

[Deebiia]

If you use life//death, life's side, and make your lands 1/1's and they had undying, would they come back into play if you sacrificed them?

If they die as creatures with no +1/+1 counters on them, they'll come back.

[Deebiia]

I was only asking because when I thought about it, wouldn't when I sacrifice them they are in my graveyard as lands and not creatures?

[Kaleo42]

While this is true those lands have met the condition of undying, they have died.

[Deebiia]

Alright, so next question. Do they come back as creatures with +1/+1 counters on them? Or comeback as lands?
