Hey thank you for the kind comments!
To answer your questions:
1. If your hand was a full house starting out and someone destroyed a card, it now scores as three of a kind instead. Make sure to make deals or protect your cards in some way.
2. You shuffle both, apologies for the mixup I will rewrite and clarify the whole document in Fukuzatsu+
