the idea is to stick with the same curve, but add better cards if you can find them.  The original deck was certainly full of crap.  Can you fit manamorphose in this deck (without ruining the beautiful curve)?  I think I'd like to try out orcish librarian, if I can get a couple. (Found one!)  Note that false orders is just a card you want to try - it does not fit the "Sligh" concept of playing cards ASAP, because you probably wouldn't play it on turn two (definitely not one).

Dwarven miner would be a good add.

Add fireblast - drop shatter?
