Even if it does end up being strong, this is a great card to print into a format where players are worried about Up the Beanstalk
Anytime you attack with one or more Goblin creatures, you get an extra 1/1 Goblin creature token tapped and attacking
Even when all you got out of this was the discard the overpayment wasn't that dramatic, and many decks were forced to adjust their builds to minimize the damage
This sorcery was essentially an artifact tutor, that had the additional cost of sacrificing an artifact, when it was cast, but it also put the selected artifact into play and not into your hand, so it was huge for some decks, because if you didnt counter the Tinker, you couldnt counter the artifact
You just need a high concentration of instants and sorceries
