A way to keep Dreadsteed's Soul

Dreadsteed was is one of my favorite cards even though I don't play it as often anymore so I was trying to figure out a way to make it as close to its current play while not being op with Defile.
 
This is the card I ended up with: http://i.imgur.com/EHCUiYd.png
 
This text makes it work with the current synergies baron rivendare, spiritsinger umbra, kel'thuzad, and mayor noggenfogger. It does mess power overwhelming up a little bit but I think the other synergies are more important. What do you guys think?
