Cubone

If you like slow but powerful Pokemon, then Cubone is worth considering. It has a good physical movepool, and the Attack stat to back it up. It has one distinct advantage, Thick Club, which gives it 30 Attack, more than almost any Choice Band-equipped Pokemon, while retaining freedom to switch moves. Unfortunately, Cubone's low Speed prevents it from being able to sweep without some form of support, like Agility passing, Trick Room, or paralysis; however, it is a great partner for all three of those strategies. Its defenses are not exactly reliable (though it can take the odd physical hit or two), so switching it in directly is a risk you may not wish to take. However, once in the battle, Cubone can be very useful at clearing out certain key Pokemon to help your team win the match.
