The most often used color for this type of deck is green, and im going to suggest adding green by cutting black ( you're not running dark ritual, and for a combo deck wanting speed you should) for some accleration and card drawing.
3 Kokusho, the evening Star
3 Darksteel Colossus
4 Tinder Wall
2 Weatherseed Treefolk (name night be slightly differnt he is a 5/3 from urza block that has rancor's ability, and thus combos well with greater good)

This adds more moxes and some tinder walls to speed you up a bit, as well as greater goods which can really draw alot of cards (11 for colossus and 5 for the others), and using either of the creatures besides Kok ( and sure we love the Kok but...) you get the tree back for (5 * X) - (X * 3) cards where X = the nubmer of red mana you can make ,and drawing 11 via Col will likely let you see another colossus or tree.
then you have random regrowth and random fling, but potentially drawing 11 makes them a little less so.
this should do pretty well compared to the other version, because the black version was disruption rather than focusing on comboing. One other random suggestion, if you wanted to still have clamps, derranged hermit is some good.
Until Ricky G rolls in his not yet dug grave, keep killing peeps with the Kok and make mine magic
