Its extremely elegant if you get stuck on mana and cant cast stuff, youre likely going to fall behind on board and get hit, which means more people will guess your cards, which means youre more likely to get Treasures, which then fixes your colors and catches you up
Worsts: Artifacts (tie), Land Value
I can really see this alongside a card like Saheeli's Lattice / Mastercraft Raptor, which you can then flip by crafting the Carnosaur out of the graveyard
By doing that, youre actually digging deep into your deck and putting yourself in a better position
[card]Scrapwork Mutt[/card] pairs very good with [card]Stinkweed Imp[/card] as you discard first and draw second, meaning that you can fill your graveyard with just discarding the Imp first and returning it to hadn due to its Dredge ability
So itd fit nicely into say my Trostani deck
