Death and revival of land-creatures
No, Horde of Notions cannot do anything with a land card that died as a creature. The key rule is rule 400.7:


  An object that moves from one zone to another becomes a new object with no memory of, or relation to, its previous existence.


If a land card like Celestial Colonnade dies as a creature, the effect that made it a creature doesn't continue to apply to the card in the graveyard. While it's in the graveyard, it's just a land card.
