As well as Tony Stark himself, there's a card for the Arc Reactor keeping him alive
It does this well and efficiently, which makes it quite strong in Eternal formats
I don't know if you're desperate to use this as a really bad rummage Artifact in a deck where you have no intention of ever attacking, but if you've got creatures and like to hit with them and also you want to discard cards, for basically any reason, there is no excuse for not running this
Thats not the best package, but its not the worst, either, and if were getting a lot of value out of the Dinosaur-ness of the card, its not embarrassing
BPhillipYork: That's potentially a lot of card draw, especially for decks that are modifying everything, that's just sort of a win more scenario
