So I think I read to deep into somethings so here it goes.
Combat damage. I sacrificed my Skavenslaves in order to prevent all combat damage assigned to attacking units. By killing off some of his units there was a point where redirected damage was coming back my way. Is this also covered my Skavenslaves ability? The combat damage also came up in the same game different scenario where I was trying to kill the Sword Masters of Hoeth which have a card description along the lines of cancel all combat damage assigned to this card. I was trying to use Lokhir Felhearts ability to assign -1 hp per development in order to kill him. In the end I just canceled the Swordmasters card effect and killed him just to make sure it was fair.
