Will you do Mane 6 tail play count for the Comics and Books of My Little Pony (IDW)?

7918875
No. I did at first but eventually stopped reading the comics. I don't even have many past the Nightmare Rarity arc, except Reflections and Siege of the Crystal Empire.

7918924
Well have no fear, this link I sent you has all of the comics. And when I mean all of them, I mean all of them. The link is when you click on Comics and Books.

Still not interested in most of them.
