Sorry, but this seems pointless. Abomination is a decent mid-hitter and is not in a real need for a buff.
Yes, but you are looking the card, how it's well-rounded and neat, and missing rest of the picture. We're talking how does it fit the game. Why did it became so useless if it is so good? You might have been right before all those patches and shards came and turned concept of "balance" upside-down. And this subject does not concern abomination itself as a single card, it also suggests it's synergies with certain strategies and cards.
On the other hand what about GoTP? Now thats a decent mid-hitter, and it's obvious why is he still commonly played. It's mid cost, mid hit, has a PASSIVE (as I am suggesting for abomination), and has good synergies (also suggesting for abomination). And I am not hearing anyone saying "nerf GoTP - he is way much better than other cards from his class". Why? Cause cards like Ghost make the game more interesting.
