Is this a back to the future reference? ._. Unity is handy when you are playing a majority human deck. You know what... I wonder if Johnny B. Goode ended up becoming Johnny Rotten? because the cards are almost identical in power. With unity, Goode does 3 melee damage to an exhausted hero or ally. Convenient if you are running a unity deck, but I don't see much more use for him unless you need a [3/2] for cost 2 alliance ally.
