Marketback Walker Bug
Opponent had Marketback Walker with two +1/+1 counters on it. I have Soul-Scar Mage. I Burst Lightning Marketback Walker, which should have removed the +/1/+1 counters from it because of Soul-Scar Mage, making it die a 0/0 with no counters on it. However, Arena had my opponent draw the cards as if he had two +1/+1 counters.

The counters annihilating each other is a state based action, so is the Marketback Walker dying for having 0 or less toughness. All state based actions of the same check are carried out simultaneously. And since "dies" triggers are leaves-the-battlefield, triggers, the game determines wether they triggers based on the game state prior to the event. Meaning, the Marketback Walker died with both the +1/+1 counters and the -1/-1 counters on it. Since it doesn't exist anymore, the game used last known information about it to determine how many cards are drawn. This includes the info, that it had two +1/+1 counters on it.
