I've made three new custom Factions based on the enemies in Kingdom Hearts:

[replacer_a]
The Heartless
The Nobodies

I built these cards with my card builder template that's in another thread in this section of the forums, as well as in the "Featured" section of my deviantart account. Feel free to give them a try and/or tell me what you think!

I thought of trying to make a Faction for the heroes of Kingdom Hearts, but I realized that they don't really have much in the way of "Commons," as the only one I could think of was Disney Castle's Broom Servants.
