i would try using ARCHFIEND SOLDIER in your deck somewhere it is a good fiend and it has 1900 atk can't go wrong with that.

Why not add a Great Maju Garzett in there?

deck devastation virus could work wonders here. try adding in two giant orcs to go along with the ddv's

there seems to be a lack of focus in the stratigy in this deck. what is it in particular you wish to acomplish? beatdown? field control? hand control? not sure where you are going with this.
