I feel like people thumbs down just to make you feel bad.
The thumbs up/thumbs down is a "I like this deck, it was fun to play against and original" or "This is remake #298347 of ghostmare. I hate you" not just something to click to make the other person feel bad.
I would have thumbs upped all of your decks, except possibly the one where the oracle gave you Fire Pillars, since they're mostly original and built by yourself.
