They represent some potentially really powerful interactions when you look at formats with Stoneforge Mystic in, because the mystic allows you to fetch up equipment cards from your deck and even put them into play for a low cost

This Jund lizard warrior lets you play cards from the top of your library based on the amount of damage it deals
If you can cheat him out on turn four, you can put the clock on your opponent one turn earlier, then follow it up with a Nani, Floodborn Pluto, or even your other Don Karnage on turn five
He immediately makes up for that by returning 2 cards from the inkwell to the player's hand, however, and can keep generating value as a great card for questing
