My second good deck was an Oty/Vulture/Boneyard deck. It depends on the situation. You'd consume a 3|4 creature to gain 1 on the Oty, 1 on the other Vulture, and 1 Skeleton. The damage technically doesn't change, but shield effects do. If a shield blocks damage, you may find that you removed a creature that break through the shield in place of others that cant. Distributing the damage may not be a good thing.
