The first to do this was none other than Jon Finkel, using the Medallion to cast spells in his Ophidian deck at 1998 US Nationals while keeping counter magic available
For those who want to experiment with the themes of this deck, but still be able to get use out of their artifacts, Najeeli, the Blade-Blossom is a five-color general who produces tokens by herself and Brudiclad would be a fitting piece of the other 99
For one hybrid mana, you get a White or Green one drop 1/1 - very cheap for two colors
Just as we started to use creature tokens structurally, we also became more comfortable with creature tokens being a core part of mechanics
