You can't try to exile three cards from your graveyard if you don't have at least three cards in your graveyard
Not only that, this card has a good amount of willpower and lore-generating capability too, since each quest gets you three lore, so it can tank some damage and still help you win the game.
Any generic elf like Elvish Mystic and Llanowar Elves are good for mana value 1, and Bloom Tender, Coiling Oracle, and Seeker of Skybreak for the 2-mana value spots
There arent any versions of Craterhoof Behemoth or Aurelia, the Warleader here
In my opinion, the final state of a well organized collection for deckbuilding should be: Sets organized alphabetically Cards in a set organized alphabetically Cards organized by color in their respective letter Cards scanned and put into a collection manager like Manabox or Moxfield This method makes it easy to find individual cards for a deck from a deck list or to browse your collection organically to build a deck from scratch
