Sequence of events:

I have Te'talca out, at 8 power (inspired with Ruby and Sword). I use Dimmid's charge ability to give her lifedrain, and then fight the AI's Claw of the Mountain God (5/4).

Both troops die (as expected)
I gain 4 life (Incorrect, since Te'talca dealt 8 damage, I should have gained 8 life)
Te'talca transforms in the graveyard (Unknown if intended)
