Seen as your already using Sun Titan , why not run a full FUNTITAN package for recursion? Namely; Necromancy and Animate Dead . Both of these allow reanimation from any Graveyard as well as being able to be brought back with the titan. Especially useful for Necromancy as it can be used at instant speed. Both are fairly cheap to get hold of.

Another good card for consideration (and one that I use in my ETB Effect, The Deck (Karador EDH)) is Skullclamp . It can provide good card advantage if sweepers are a big thing in your meta. But even so, just clamp it onto a little guy and watch the cards come rolling in.

You might also want to consider some land fetch creatures. Farhaven Elf and Yavimaya Granger both come to mind. Yavimaya Elder is also pretty decent.

You may also want a way to deal with indestructible creatures. card:Black Sun's Zenith, Path to Exile and Oblation are all fairly useful. Additionally, in these colours you can run both Mortify and Putrefy which with their multiple modes have saved my ass more times than I can remember.

Finally, I'd really take a look at Acidic Slime and Disciple of Bolas . Theyre both awesome in a Birthing Pod chain. Sylvan Primordial and Sepulchral Primordial are also really good.

Hope this helps!

i don't know if an average of $10 is too expensive, but for G/B gravestrat i suggest Lord of Extinction. he gets retarded huge in multiplayer.

Maybe, I'll have to consider. Thanks for the idea!
