Midler

When Midler enters the battlefield, reveal cards
from the top of your library until you reveal an artifact card. Put that card into your hand and
put the rest on the bottom of your library in a
random order.
High Priestess — {1}{u}, Discard a card: Target
artifact you control becomes a copy of
another target artifact, except it's a 2/2 artifact creature with "This creature can't be blocked."
