For those of us who can't post in the Type 1 Forum here a link to an article on UB Mask
http://www.themanadrain.com/forums/viewtopic.php?t=17489I think the biggest problem with UR mask is that you can just replace the mask and dreadnaught with dragon/animate and you get a combo that wins instantly instead of in 3 turns. ELD's version is better because the welders protect it, but the dragon combo can just use that slot for more disruption and protect just as well.
