Cwn, Vengeful Annwn

When Cwn, Annwn Beast enter the battlefield, create three 2/2 Cwn Annwn creature tokens with, "When this creature enters the battlefield, it fights up to one target creature you don't control. If this fights a non-human creature this way, then Cwn Annwn and other dogs you control get Deathtouch and Indestructible until end of turn."
