Scorpion God + Amass bug
Using The Scorpion God's ability on a 1/1 Zombie Army created with amass draws a card, even though the creature has no -1/-1 counters on it.

Not a bug.
The relevant rule here (from the comprehensive rules at https://media.wizards.com/2022/downloads/MagicCompRules%2020220908.txt ) is 704.8
"If a state-based action results in a permanent leaving the battlefield at the same time other state-based actions were performed, that permanent’s last known information is derived from the game state before any of those state-based actions were performed.
Example: You control Young Wolf, a 1/1 creature with undying, and it has a +1/+1 counter on it. A spell puts three -1/-1 counters on Young Wolf. Before state-based actions are performed, Young Wolf has one +1/+1 counter and three -1/-1 counters on it. After state-based actions are performed, Young Wolf is in the graveyard. When it was last on the battlefield, it had a +1/+1 counter on it, so undying will not trigger."This is the same situation as the example given there -- the army is treated as having died with a +1/+1 and a -1/-1 counter still on it.
