Keep in mind, when you ready Aurora Waking Beauty through her ability, you cant Quest or Challenge with her, but you can Sing, so potentially, you can play two 5-cost Songs in one turn
The two Id like to talk about today are Collectors Edition and World Championship decks
I could just about buy an animated building as within greens wheelhouse if the lore was right we did get Awakening of Vitu-Ghazi, after all
Senseis Divining Top is perfect here since, if the top three cards dont include an artifact, you can always tap the Top to draw a card and put the Top on top of your library before you mill, ensuring that you can draw the Top from the mill effect and clearing the next two cards off the top of your library
Unlike so many of the other cards in this list they replace themselves and frequently get cycled away without being used to help fix your colours at all
