What is the flight safari zone Pokemon trick?

The flight safari zone Pokemon trick is a glitch that allows players to find and catch any Pokémon in the Safari Zone without having to encounter it there and waste Safari Balls and turns doing so. To perform this trick, the player must first select the Pokémon they want to catch at the Safari Zone hut, then leave and save their game. The player must then return inside and find the Pokémon to be caught, and throw one Safari Ball at it, attempting to catch it in 3 turns. The player must then fly back to the Pokémon Center, heal their Pokémon, and find the Pokémon they intended to catch again. Now, it has 1 health, so the Safari Ball will 100% catch it, which it was not likely to do originally.
