Compatible? Really? I thought those two get shipped precisely because they clash. EDIT: I read that as Flutterdash, sorry.
my own personal favorite would have to be either TaviScratch, Berry and colgate, or Ditzy and Carrot Top (fluff)
Just about any heterosexual pairing. I don't really like f/f ships anymore because that's practically all there is. M/M ships usually arn't bad Spike X Applejack. It's perfect I tell you!
Equestrian females outnumber males 5-1. The Changelings chose to invade Equestria due to it's abundance of love. That implies either bigamy or lesbianism.
Changelings feed off love, but there's many different types of Love. Who's to say a Changeling couldn't feed off Storge love, or Phileo love? Nobody ever said it could only be Eros love... Just a thought.
Cheerilee x Big Mac Cadence x Shiny Mr x Mrs Cake Any Foal x Any CMC/Filly As for the Mane 6.. I've got nothing. I'm a very boring person. I like to stick to what the canon says.
Pinkie Pie X Fluttershy After finding an incredible ask blog, it became my favorite ship, because even though they are different they still find so much common ground.
My favorite shipping? Well I only use UPS as long as their available. I don't like The US postal service. They don't ship on Saturdays. Although UPS usually delivers around 2 pm. USPS delivers in the morning
Definitely Cadance and Shining Armor. I was shipping them way before it was revealed they were getting married. I'm so good at this.
