Tormod the Desecrator should not create tokens when reanimated
If you cast Blood For Bones and return Tormod, the Desecrator to the battlefield as part of the resolution, he creates a token for his own return. He should not give a token if he is reanimated.
This is incorrect behavior, and should be fixed. Also note that this will apply to Quintorius, Field Historian once he is legal.
Per the CR, section 603.10:
Normally, objects that exist immediately after an event are checked to see if the event matched any trigger conditions, and continuous effects that exist at that time are used to determine what the trigger conditions are and what the objects involved in the event look like. However, some triggered abilities are exceptions to this rule; the game "looks back in time" to determine if those abilities trigger, using the existence of those abilities and the appearance of objects immediately prior to the event. The list of exceptions is as follows:
Some zone-change triggers look back in time. These are leaves-the-battlefield abilities, abilities that trigger when a card leaves a graveyard, and abilities that trigger when an object that all players can see is put into a hand or library.
