The Brony Show - Ponies, Traps, and Deck of Cards

Trixie was building her deck of cards while her corrupted form captured Spike the Dragon, Twilight Sparkle, and Starlight Glimmer and trapped them by encasing them in their crystal prison. Rainbow Dash and Dr. B heard a distress signal from Twilight before she was trapped in a crystal via magic. They decided to recruit SMG4 and rush to a cave. Once inside, they do not realize that the corrupted Trixie has a plan for these heroes.

Note:

Trixie Lulamoon, Twilight Sparkle, Spike the Dragon, and Starlight Glimmer are the characters of My Little Pony: Friendship is Magic
