To defeat Cinnabar gym, get 6 Gyrydos, and have them know aqua tail, earthquake,rain dance, and hydro pump. ( Hydro pump is optional) Put all six on the top, and make one use rain dance until it starts raining. Switch this Gyrydos to rain dance when needed. Then Have them all use Earthquake until Moltres comes. Switch all but one to aqua tail and make them keep attacking until moltres faints. Then, one by one, move the pokemon to the bottom. I suggest you swich them to earthquake at this point. Don't use any super potions unless necsasary until now. Have some gyrados switched to aqua tail. After only a few pokemon remain, switch your left over gyrados to aqua tail. Make sure you have it raining. After some time, Entei should be defeated. This way can take a few tries, but it helps.
