Counting all cards that care about Dungeons, including ones that Venture and ones that care about if you've completed a dungeon, there are a total of 41 cards
Paying the handsome sum of $1,000 (and $22 for shipping), Wurmcoil Engine number 217/500 was bought without contest
Not only does the pair pack solid base stats, it also draws a card when it enters play and attacks, with the option to discard lands as well to remove problem creatures
My eternal regret is that the deck cant also play Colossification
How much cards are getting played are not always a big factor in their value, it can sink a card
Other Removal/Interaction I did still try to squeeze in some basic meat and potatoes cards that any decent Commander deck needs
