Use the Portal to return any of these to your hand then cast them to destroy an opponent's creature.

use the dark hatchling on the ancient silverback because it's a 6/5 regenerator

Just cast out your dark hatchlings to destroy creatures then use them however you will sac em, block with em, whatever, then use no rest to bring em back and destroy more creatures.

When Hatchling is in the graveyard bring em back with the queen, destroy a creature, untap the queen and do it again....
