Whenever one or more creatures you control and/or creature cards in your graveyard are put into exile, you may choose a creature card from among them. Until end of turn, target token you control becomes a copy of it, except it has flying.
+2 : Surveil 2, then exile a card from a graveyard.
+1 : Create a 1/1 white and black Spirit creature token with flying.
−2 : Exile target creature you control. For each other player, exile up to one target creature that player controls.
If a creature card that was exiled is no longer in exile when Kaya, Spirits' Justice's first ability resolves (perhaps because of Pull from Eternity or a similar effect), you can't choose that creature card with that ability.
