Question about ignition effects and Gorz What would happen in these 2 situations:

My friend summons GK Descendant while he already controls 3 GK Recruiters, and I have 4 cards in my back row. Then, I chain Torrential Tribute to his summon.
I understand he has priority, but would he be able to tribute ALL 3 GK Recruiters to take out 3 cards in my back row after I flip Torrential? Also, would he even be able to activate Descendant's effect if he chooses not to initially and allows me to flip torrential?


If my friend and I both control our own 2000atk monsters and I suicide by attacking his, am I able to special summon Gorz from the damage? I remember from back in the day I would suicide into a card and chain waboku, allowing my monster to stay alive because it was considered battle damage.

Thanks!
