Santa's Sleigh

Flying, Vigilance
When Santa's Sleigh attacks, each player exiles
the top card of their library. Until the end of
your next turn, you may cast those cards and
you may spend mana as though it were mana of
any color to cast those spells.
Crew 2 (Tap any number of creatures you control with total power 2 or more: This Vehicle becomes an artifact creature until end of turn.)
It's high time Santa began to take a little too...
