So, what's wrong here? Well, the big concept was to make a massive Kilnmouth Dragon and that right there is a problem. Because it's a Glory of Cool Things card: you could have a 14 power dragon, right?

Then why aren't you just attacking with it? Why tap it to do 9 damage to something?

Which is a bit of the issue with the entire deck; all these big creatures and they don't just revolutionize the board when they enter. Which, if you're paying six mana for something, ought to do that.  

And that's really the issue here: when this  deck gets to 6+ mana, it doesn't play cards that brick the opponent's board. 

So I'm using all the cool stuff here and putting into the Ur-Dragon deck. It needs to be updated anyway, what with all the cool new Dragonstorm stuff.
