1.If i special summon from my deck bone crusher with the effect of pyramid turtle,during the end phase it will be sent to the graveyard?2.If i control a zombie world, then special summon kasha and send all monsters from the field back to the deck,will kasha gain atk points from my opponent's monsters,because of the effect of zombie world?3.If i destroy one of my opponent's monsters with goyo gurdian and that monster cannot be special summoned,will i control it?
1. No, because it wasn't special summoned by its own effect. 2. No, because zombie world only makes them zombie when on the field and in the graveyard. Therefore, they don't count as zombies when kasha returns them to the deck. 3. No, you won't because goyo special summons the monster from the graveyard.
If it cannot be Special Summoned, then you cannot take it, because Goyo Special Summons from the Graveyard.
