One thing I haven't seen mentioned yet is that instant speed removal blanks this guy for a turn. While aetherling can certainly protect himself and grind out the game, he's not quite as dependable as morphling since morphling can instant shroud and still swing in, especially when the game is really tight (and down to a turn). if you're on the line with aetherling and go through the motions of pump, etc., an instant speed doom blade will blank all the mana you just invested for a big hit, preventing you from casting other threats, leaving countermagic open, etc.
but i do like the fact that he can dodge your wraths.
