I banish you because if Twilight was playing this game, she would have a heart attack right now!
I banish you for not saying "Twilight", and "best pony" in the same sentence.
I banish you for misspelling Luna.
I banish you because you assume best pony is either Twilight or Luna. Clearly you're both wrong and it's Sunset.
I banish you for thinking Sunset Shimmer is the best pony, when all ponies are equal and everypony should be treated as such.
I banish you for your Starlight Glimmer way of thinking.
I banish you because Starlight Glimmer is actually best pony (post Twilight getting her wings).
I banish you because you think like Starlight and don't think Lyra's the best.
I banish Blue_Sky for banishing someone who was previously banished out of order, and I banish DaturaDaydream for having an opinion that is different than my own.
I banish you for being ban happy. 2 in 1!?! That's a new record.
I banish you for trying to tell people what the record is.
I banish you because your comment got me banished at a different point just because it looked like the latest one to me but apparently wasn't and this is a long run on sentence.
I banish you for said run on sentence.
I banish you for not giving us more of your North Dakota air. I wanted the snow to stay, not melt the next day!
