My additions mostly involved being extra greedy. Zola the Gorgon for ultimate greed, High Priest Thekal (goes really well with Reno), Eadric the Pure (have always loved this card and if you're way behind it's fun to shut your opponent down in one turn), Djinni of Zephyrs (super slow but if you can get him rolling you win and it's a just for fun deck anyway).
I took your deck and made a few small edits with cards I really like.

Very fun deck! I took out the two Stonehill Defenders and added Archmage Vargoth (as per the above suggestion) and a Rotten Applebaum
For serious greed, consider adding Da Undatakah as well
