Atlach-Nacha

When Atlach-Nacha enters the battlefield, put
an egg counter on each creature you don't
control. For as long as that creature has an egg
counter on it, it gains "When this creature dies,
each player who controls a permanent named
Atlach-Nacha or has a card named Atlach-Nacha
in their graveyard creates a 2/4 Black Spider
creature token with reach."
Sacrifice five Spiders: Return Atlach-Nacha from
your graveyard to your hand.
