Example: Elsa Snow Queen , originally from The First Chapter , returns in Fabled as an Epic rarity card
The mechanic saves you from really having to cast self-mill spells at all: you just mill a little to get them into your graveyard, then start replacing draws for free chunks of three, four, or five cards flipped over from library to grave
And of course, for a project of this scale and size, we've included some pretty awesome treatments, not only to the cards in the main set but several Commander staples as well
Promo cards are often limited in availability, so take the chance to grab one when you can
But as long as it's valid, the self-replacement effect happens automatically and immediately when the trigger resolves
