Papyrus

Spaghetti Lover. (Papyrus gains double the power and toughness from sources with the pasta subtype.)
{u}: You're Blue Now! (Remove flying from a creature.).
When Sans dies, transform Papyrus.
When Papyrus has a Determination counter on him and you are also controlling Sans, sacrifice them both and summon Sixbones from your hand, library or graveyard.
"You're blue now! That's my attack!" -Papyrus
