Nardo, Not All There

If you would draw a card other than the first card
you draw each turn, instead shuffle Nardo, Not All
There into its owner's library. Then, exile cards
from the top of your library until you reveal a spell
with higher converted mana cost than Nardo.
Play that card without paying its mana cost. Shuffle
the exiled cards into your library.
"Huh? Oh, I don't know. I'll go get my supervisor."
