Hello! How do effects that double damage interact with damage assignment? For example, if a 3/3 is blocked by two 2/2, and a furnace of Rath is on the battlefield, will both blockers die? or only one, because I must assign 3 damage to it (and 1 to the other) , and THAN damage is doubled?
Effects that double damage double the damage when it’s dealt, not when it’s assigned. This means that in the case of trample or multiple blockers, you’re going to have a lot of overkill going on.
In the situation you describe, you can assign 2 damage to the first blocker and 1 damage to the second blocker. When the damage is dealt, the first blocker will be dealt 4 damage and the second blocker will be dealt 2 damage. Both will die, as will your creature which is dealt 8 damage.
