I'd just like to confirm that you could not use Spiritomb's "Darkness Grace" to evolve a Baby Pokemon because the "evolving" card does not say "evolves from".
Similar to this ruling about Rare Candy:
Q. Can I use Rare Candy to evolve a Baby Pokémon into its next stage? What about the newer forms of babies that are considered "Basic Pokémon" but have the "Baby Evolution" Poké-POWER?
A. Rare Candy states if you have a card that "Evolves From" your Pokémon There are currently no cards with text saying "evolves from" its baby form, so Rare Candy will not work on any form of baby Pokémon (Oct 23, 2003 PUI Rules Team)
