Looking at this, I thought a lot about the most recent set excluding Final Fantasy, Tarkir Dragonstorm, and how this card fits in so well with those recently released decks and strategies
I can see a nice strategy with this commander going for commander damage and then being rewarded with a body when its eventually killed
The best Commander decks are synergistic with their commander but not completely dependent on it
Opponent Declares Defense : After you announce your attack, your rival chooses the defense, indicating which defending creature is blocking which attacking creature
You can grab a regular sleeve, the occasional Secret Lair art sleeve, or an exquisite sleeve, which serves the same function but features nifty animations instead of a static image
These cards alone could make a powerful deck, especially when combined with existing Goblin cards in Magic: The Gathering
