Ability idea: Pierce

If the attacked creature gets killed by the attack, the remaining damage goes to the creature or hero behind the first attacked creature.

Example: You have a 3/0/2 creature with pierce. The enemy has two 1/0/2 creatures in the same row. If you attack the first creature, it dies, but you overkilled it, you still has one damage, what goes to the second. Same happens if all creature dies, in this case, the enemy hero gets the remaining damage. Very cool to combine with swift and attack increase. A little similar to Charge, but that can't damage heroes, on the other hand, that one doesn't get weakened by the first creature. Opinions?
