During your upkeep, pay or bury Arcades Sabboth. It is not of creature type Dragon. Make even your weakest creatures, the best of defenders.
Arcades is more of a novelty than something to build a deck around.
Its casting cost, while reasonable for its abilities, is far too high to make it likely that you're going to get it into play in time for it to matter in most games. Still, if you can do it, it's worth it. In addition to being huge, Arcades, has the abilities of a Holy Armor and a Castle built in. Arcades Sabboth is one of the five Elder Dragon Legends. Arcades Sabboth is a difficult creature to bring out, but his abilities offer white another card that acts very similar to a Castle.
