The Fourteenth Doctor

When you cast this spell, reveal the top
fourteen cards of your library.
Put all Doctor cards revealed this way into your
graveyard and the rest
on the bottom of your library in a random order.
You may have The Fourteenth Doctor enter the battlefield as a copy of a
Doctor card in your graveyard that was put there
from your library this turn.
If you do, it gains haste until end of turn.
