Dwarf on the Flask

When Dwarf in the Flask enters the battlefield,
draw a card then scry 1.
{5}{w}{u}{b}{r}{g}, {t}: Choose a creature and exile
the rest. Then put X +1/+1 counters on that
creature, where X is half the number of exiled
creatures rounded down. That creature gains
ouroboros. Create a creature token that is an
exact copy of that creature except it is a
homunculus in addition to its other types.
