I second
Goblin Rabblemaster. Worth it for a $15 card, as he has some awesome Token-y powers.
Goblinslide can get expensive though, and I would look into a Staff of Flame Magus. Despite it being a goblin token deck, if you can't get things out until midgame you could be in a stitch on health. I try to always run at least one or two if I can so that my tokens generate me life. (pretty sweet when you get 126 tokens on field.... It was a long game)
