See Ophidian Dreams for some explanation. We might want this card to draw more cards and/or put another creature on top of your library, and, consequently increase the cost. Maybe not. Also, I like that name, but it's too obviously blue or maybe white.

­Footbottom Feast is this but a 3-mana instant rather than a 2-mana sorcery, but that has fewer restrictions. How about changing "creature cards" to just "cards"?

I dodged "cards" for the same reason they didn't reprint Regrowth in 2012. Time Walking to victory is too easy when you got a spell that returns things that cheaply. It also kind of bugged me that the Enlighten mechanic was redundant, and so wasn't graveyard recursion. I think that stayed my hand from making the card relevant, though, that's probably a terrible reason to make bad cards.

We could steal the 2012 team's answer and just return two permanents, ala Nature's Spiral. There's probably a reason why those cards are always uncommon, but I'd be willing to bump this card to uncommon and replace it with another cantrip, say. We could also steal Innistrad's answer to redundancy and return two cards at random from your graveyard ala Make a Wish. I find the idea that you have the potential to screw yourself up kind of funny (Let's see... from a full graveyard, I randomly return to my hand and the top of my deck... the two lands you made me discard on round 3. Great.) I don't know if that is good funny, or bad funny. I guess both.
