When Ultron III says he cannot take damage while a Drone is in play, what happens if one effect defeats the last Drone and damages him at the same time?

Question

Accepted Answer

Ultron cannot take damage while any minion is in play, so simultaneous damage to a minion and Ultron does not hit him. Minions must be defeated first; overkill still works because the minion is defeated before excess damage is applied.
