Voltron Glissa and recur artifacts like a madman.
I had a deck similar to this. I ran more interesting artifacts like those I suggested above. Really you have to evaluate the strength of each as it is played and what it does in your hand. I especially loved cheap artifacts that required little mana dump and could come back and do crazy things.
If we're talking stupid combo things we can go Memnite +Grave Pact +Arcbound Ravager . It's a free wrath that only kills your opponents and prevents regeneration and protection from player. Oh did I mention you get an insane amount of tokens on arcbound ravager? Grab him a pair of Swiftfoot Boots and go to town on the table. Probably one of the most degenerative combo's I've ever done with my glissa.
Also if you love the mindslaver effect like I do grab yourself a Sorin Markov because free mindslaver is free.
Also with the artifacts bouncing to your hand you really need mana to play them quickly and get second uses. For this reason I feel Sword of Feast and Famine is an auto include for untapping lands.
Hatred is an easy win condition. Filth is good tech for swamp matchups also combos well with urborg. Phyrexian Obliterator makes opponents sac things. Painful Quandary stops storm and combo. No Mercy makes you less of a potential target during political shenanigans. Dread is a creature no mercy.
Overall I think the list needs some tweaking to ensure you will be fast early, last out the midrange aggro, and finish out the combo pillow fort players.
