I had 3 Elemental tokens from Grove of the Guardian on the battlefield. One of them was enchanted with Rancor. My opponent had a Mounted Archer on the battlefield. I attacked with the three Elementals and he blocked all three of them with the Archer. How much damage gets through? Clearly the two unenchanted Elementals are stopped completely. But does the one enchanted with Rancor only deal 7 damage to my opponent or does the full 10 get through? Why?
