I have a question regarding MTG rules and how can be applied. In this case, it's about lands that can become creatures. I was checking this one-mana EDH deck, and I saw that the Commander has this ability:
Horde of Notions {W}{U}{B}{R}{G}
Legendary Creature — Elemental (5/5)
Vigilance, trample, haste
{W}{U}{B}{R}{G}: You may play target Elemental card from your graveyard without paying its mana cost.
Even the oldest treefolk was but an acorn when Lorwyn’s first mysteries were born.
I was wondering: if the land was killed and sent to the graveyard while being a creature by any X reason (say "Lightning bolt"), is it possible to retrieve it back using this ability? For example, Celestial Colonnade can turn into an Elemental until end of turn.
