I didn't get a screenie, but I was playing a Vampire deck in the trainer. I stole one of Fire Queen's Feral Bonds, and I noticed that as my creatures attacked, I gained +6, +1, +1, and +6 life -- 6 from each Vampire (which was right, since I had an Eclipse up), and 1 from each Parasite, which would be from Feral Bond.
But I never gained +1 from the Feral Bond for the Vampire's attacks. I think the healing from the Vampires overrode the healing from the Feral Bonds, which totally shouldn't be the case.
Should note that this was in Trainer. IDK if it would happen in the 'real' game.
