Decks For Characters, Good Decks?

So, I put together three decks looking around DA for custom cards, and I've created three different decks, all of which have folders in my favorites. If you're interested in seeing them, I'll give links so you can judge for yourself as to whether you think there's a character who these decks would fit. Also, before you say it, yes, I'm well aware that all these cards are altered versions of official cards, but I still like the alterations.
