Theyre easy to set up, simple
You spend a full turn to cast your Duskdale Wurm, and I spend a sixth of my mana to Unsummon it
It's an MTG commander who wants to be creating and cracking food at all times, since Ragost untaps on each end step when you gain life, and has a tap ability that sacrifices a food to blast everyone at the table for three damage
Despite the reprints, though, the legendary creature still has an MH1 foil version priced at almost $100
Despite all that, this is the best single card in this archetype by a much larger margin than I suggest with the out of ten scale
Really you want to convert dorks into cards, mana or damage and so this has very limited appeal
