Well, in the early sets, Puppy decks weren't all that viable. Puppy cards had a resurgence in the last 2 sets, but I haven't messed with them enough to see if they're that competitive yet. But, I remember that the Puppy cards lead to a lot of swarm decks emerging, catapulting Rock Star Stitch into popularity.
Combine that with any King at Pride Rock, and you could flood the board.
