Giles de Rais, Bluebeard

As Rukarumel enters, choose a creature type.
Slivers you control and nontoken creatures you
control are the chosen type in addition to their other creature types. The same is true for creature spells
you control and creature cards you own that aren't
on the battlefield.

{3}, {t}: Create a 1/1 colorless Sliver creature token.
