- 1 Vigor (If damage would be dealt to a creature you control other than Vigor, prevent that damage. Put a +1/+1 counter on that creature for each 1 damage prevented this way.)
- 1 7/7 creature with Trample (Attacking)
- 1 1/1 creature (Blocking)
I assign 1 damage to the blocker, and the rest of it (6) to my opponent. As our creatures take damage, Vigor's ability triggers and Garruk's Horde gets a +1/+1. How much damage does my opponent take: 6 or 7?
Now to further convolute the question: what happens if the blocker was replaced with an Abuna Acolyte? Knowing that it could tap to prevent the 1 damage that I assign it, must I assign it 2 damage? If I only assigned it 1 damage and it tapped to avoid that damage, would it successfully block me?
