Okay so i am going to try and make this as clear as I can, I apologize if I lose you along the way.
*** 1st Hypothetical situation***
I am playing a force master. I mind control your knight of westlock. I then reveal an essence drain on the same knight of westlock. During the upkeep phase (because I control the creature and enchantments) I choose which upkeep to pay, or not pay, first. I choose to let the essence drain go first and do not pay the upkeep. The creature dies. Awesome (expensive) but the closest thing this game has to an instant kill! (which I think it is?)
***Enchantment Transfusion***
So by the wording in the FAQ (see decoy), enchantments are ALWAYS revealed when destroyed. So Enchantment Transfusion can send any enchantment to a new legal target when that creature dies because it is revealed and the effect happens when it is revealed.
***Healing Charm and Bull's Endurance***
Another interesting situation that occurs when the creature dies. Enchantments are forced to be revealed, and the creature heals for the amount on 4 die of damage and / or gains +4 life.
The cool part here is that damage and destruction, then subsequent heal, happens during the damage and effects stage. Creatures do not get destroyed at the end of the action or round, but whenever the damage dealt equals / exceeds their life total, which triggers the enchantments to be revealed, which changes the life total before the phase ends.
So could either, or both, of these cards save a dying creature?
In my gut I am going to guess that they can not, but I figured that I would post them up and see what the general consensus was.
Thanks for the feedback
