I can see a lot of EDH (Commander) players wanting this card in much the same way they want the older Hedron. It's a pretty decent mana rock that replaces itself and gives you a plus-one when you need it. Is it Constructed playable? The older Hedron never really did at 6 mana, but this one being much lower on the curve potentially could. Personally, I think it's just going to see Limited and Commander play, but the latter means that foils could be in the realm of $2-3 given time. Definitely a card that I like.
