Wirecat, you so bad! Granted, 4 colourless mana creatures aren't all great (in fact, most are pretty bad), but this thing is useless. It gets taken out an enchantment of all things! It doens't even have to be enchanted; an Urban Burgeoning stops this card dead in its tracks. Not much else to say about this other than it's bloody useless and should not be used in any circumstance.
Pros: 4/3 for 4, it exists
Cons: Arrested by all enchantments even non-Auras
