Death Tyrant card has the following ability:
Negative Energy Cone — Whenever an attacking creature you control or a blocking creature an opponent controls dies, create a 2/2 black Zombie creature token.
We had a situation where the Death Tyrant was goaded into an attack, and it was blocked, and dealt enough damage to die. What we're not certain about - is whether it's ability above would still generate a zombie token for itself and any other attackers the player had that died in that combat round.
Reading the rules, we wouldn't be surprised if it was either yes or no. We're just trying to figure it out for the next time.
