I don't understand Little Cup rules. I thought that the participating Poke'mon was not allowed to know moves that it could learn by leveling up, but in an an answer to a previous question for a Little Cup Moveset for Ponyta(I'll add the link if I find it), the answer suggested either Flame Wheel or Fire Blast! Doesn't Ponyta learn those moves by leveling up? Did I not understand the Little Cup rules?
EDIT: Sorry, it was actually Flare Blitz, bu I'm pretty sure Ponyta learns that by leveling up, too. Here is the link. http://Pokemondb.net/pokebase/94619/what-is-a-good-lc-moveset-for-ponyta
