If you end up running some of the Goblin token producers like Dragon Fodder or Goblin Rabblemaster, Castle Embereth plays very well alongside them
[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
In Magic: the Gathering there are few sagas more iconic than that of The Brothers War
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

So itd fit nicely into say my Trostani deck
