Gisa & Geralf vs. Prized Amalgam

PajdaCZ

When you cast G&G, the next 4 creatures in your library are destroyed.
When you cast PA, it returns himself from the graveyard when a Zombie comes into play.

So obviously this combination of cards should create a 8/8 defender each round (if destroyed previously). Even bigger defender if you have more PAs in a graveyard, but G&G puts exactly 4 there when they enter the battlefield.
But only one PA comes into play from the graveyard, creating a 4/4 defender only.

Or am I getting this game mechanic wrong?

G&G pulls creatures out of your library, including copies of itself. Pair that with L1's third ability, and let your imagination run wild...

Ah true, that makes sense if it also pulls itself, so PA can vary from 2/2 to 8/8.... shame!
