What T-nuts said Asidoh.
As for the aerial hammer, I don't know about you guys, but I use that thing all the time. Actually, I mainly use it as a retreating empty SH reverse hammer, or even just a bunch of empty hammers when they're off stage near the edge before going to gimp them. It gets the fear of the puffball in them, and occasionally even connects. Big thing is though, after a while they start to expect the hammer almost as much as a Bair, and the timing for shielding/avoiding the two are so incredibly different it starts to mess them up.
Also, Gonzo combo was originally Fthrow>Uair>Fthrow>Uair>Fsmash I believe, but now people are starting to DI out of it, and it became Fthrow>Uair>Utilt>Bair. Just don't expect them to be foolproof.
Another cool combo is Dthrow>Utilt>Utilt>Usmash (Give or take a Utilt depending on DI), or even if they don't expect it Dthrow>Utilt>Dair (use the Cstick for it so you can DI backwards and avoid hitting them with that shockwave hit at the end)>any throw or tilt (I usually do Ftilt or Dtilt to Fsmash).
That's my 2 cents.
