Shuckle

Shuckle can be found at a lot of the beginning maps so look in the pokedex to see where you can catch one. Now Shuckle may seem like a weird choice at first, but if you use him right, Shuckle will be one of the best pokemon you will ever see. A good Shuckle should have 25+ ivs in defense, sp. defense, and hp. To ev train a Shuckle right you need to have 252 evs in hp and 129 in both defenses. To use a Shuckle right, you need the right moveset. I personally recommend using wrap, infestation, rest and double team. Wrap: Causes bleeding which will take around 15% health from the poke each turn. Infestation: Causes poisoning which takes around 10% health from the poke each turn. Rest: Recovers a lot of health. Double Team: Increases evasion so the opposing poke can't hit you.

Shuckle also has the ability Radiation which takes 10% health from the poke each turn

Using Shuckle for Hunting: Shuckle can be a great poke to use for hunting. Radiation will take 10% of health every turn, so just keep using double team and lower the pokes health. Now be careful. If the pokes health gets below 10.2%, it will die the next turn, so switch out pokemon. I will tell you what poke/pokes to switch out to next thread.

All in all, Shuckle is great for beating gyms and hunting. Use it right, and you can become a pokemaster.
