Nebetka, God of Eternity

Menace
Whenever one or more cards leaves your graveyard,
put a worship counter on this card.
{2}{b}{g},{t}: Return target card from your
graveyard to your hand. If the targeted card is a nonland permanent with converted mana cost less

counters on this card, return it to the battlefield instead.
When Nebetka dies, put it on top of your library instead of putting it into your graveyard.
