Saskia, the Godmother of Tarja

Indestructible
As long as your devotion to red and white is less
than five, Saskia isn't a creature.
At the beginning of your turn you can choose up
to one target from exile. Return that card to the
battlefield under its owners control.
{x}{r}{w}: Sacrifice X Nappy creature token. Saskia
deals twice X damage to any target.
