Quote from IMorphling89 »I think this is going to be an excellent constructed card for all sorts of combo decks in Modern, Legacy and possibly even vintage (Paradoxical Outcome storm bounce the artifact while the trigger is on the stack to draw a card and return it to your hand - anyone? Paradoxical Outcome also runs a Tinker for Bolas's Citadel but in a pinch you could Tinker for this and activate it to get Tendrils of Agony.)
In fact, I feel there's a chance this could be the next Hogaak, Arisen Necropolis and end up banned in modern.
Not to mention how perfectly this slots into Urza, Lord High Artificer Thopter Foundry Sword of the Meek combo with Karn, the Great Creator to both shut down your opponent's activation of this and/or tutor up the combo pieces. The fact that Goblin Engineer fits perfectly into all of this just adds to the silliness.
Ok, time to go to the Modern forum for theory crafting on artifact combo decks...
As a cube card, it could go either way.
