I am double battling. I have a tyranitar with sand stream so it can help my shuckle. My shuckle has the ability contrary and needs 4 moves. my options are flash, trick room, toxic, rest, substitute, power split, shell smash(what moves? or if you have other move ideas). and what item? and if this is the wrong place to ask this can some one steer me in the right direction, im still a noob.
