ARTHANASIOS: I dunno, restricting it to life creatures seems too narrow. Can you provide a gamebreaking example to argue?
Oh and if you haven't noticed, I have changed the effect such that your opponent has to kill the creatures for the extra attacks to kick in (so the spark combo is no longer possible) and clarified this card's interactions with adrenaline.
I'm keeping the ability active, since I feel this card is already slightly on the strong side, so making it loboable should be enough to balance that. I could be very wrong about this though.
The problem here is more thematic-wise than mechanic-wise. The Mother Bear represents here a type of nature's wrath combined with mother's instict to protect/avenge her children. Because of that, it is obvious why the Mother Bear would be angry if a
creature was killed, however why on earth should become angry if a Skeleton or a Maxwell's Deamon or a Minor Vampire of yours was killed by your opponent? It just doesn't make sense to apply to any kind of creature.
About the effect being triggered only if the creatures are killed, yes I agree with you here. But I still think it's thematicaly akward for the bear to strike more times per turn due to wrath for an

creature. On the other hand, a

creature killed by your opponent seems to be a fair excuse.
