Here we have another design where the characteristic box is removed. Mulgor doe not have any abilities or hindrances but does have a few attributes (left white symbols). The background color shows the rarity and the colored circle (bottom left) shows which class it is from.
Underworld Worm is just a tad different, other than having the characteristics box, we also see the type of unit it is (bottom right). As noted by the icon, this unit is a Rock unit. Other types such as Flesh, Mechanical, Dark, Fire, etc. will also find themselves here.
We are getting a bit crowded on the tile but this type statistic will allow for better synergies... example "This unit can give any Mech unit +1 Attack."
Let me know your thoughts....
(ignore the size difference... They will be the same size, the file shrunk for some reason)
