Looks pretty solid but that ground, and fighting weaknesses is to consider, and with a need for hazard support for sandile.
Meowth can take out weak pokemon such as mienfoo if it isn't holding and eviolite or use bite on those switch in ghost types, he can U-turn to magnemite or someone else, and return for more power. Croagunk supports water moves coming into at ponyta, or aqua jet to sandile, and a great counter to other fighting types out there to bulk up and sweep. Shroomish is here to cause chaos with it's status inflicting moves, and it counters sand teams for a plus usage, Ponyta is a sweeper to play mind games with predictable switch ins with life orb to boot it up and its flash fire helps with will-o-wispers coming at croagunk, and hekps magnemite also, and sandile is there to do damage with moxie to revenge kill, then get rid of others if its neutral damage, no immunity to avoid waasting the attack boosts for him. Magnemite is a Trapper gets rid of meowths counters very well.
