Finale of Eternity

If you target a creature you own and X is 10 or more, that card will be among those returned to the battlefield.

If some but not all of the target creatures you choose are illegal targets as Finale of Eternity resolves, the legal targets are still destroyed and, if X is 10 or more, you still return cards to the battlefield.

Any abilities that trigger on the target creatures dying or on the creatures returning to the battlefield will all be put onto the stack after Finale of Eternity has finished resolving. If it’s your turn, your opponent’s triggers resolve first, even though their creatures died before your creatures entered the battlefield.
