mtg ur dragon commander deck The Ur-Dragon Broodmate Dragon The Ur-Dragon MTG - Commander

This was later vindicated with the commander decklists having been spoiled as I was writing this

Everything radiates from the center: the light, the branches, even the roots

Being able to neutralize some of the best creatures in the formatlike Avacyn, Angel of Hopewill go a long way to enacting your Horror-laden plans

Dredge decks sing with this around, and its not bad in Cube either

The second choice seems the more useful option, but the two cards from the top can be good in certain scenarios

As for Arcane Artisan, I used to like it mostly as an enabler that dodged some of the hate-cards such as Containment Priest, as well as providing a non-symmetrical Show and Tell effect
