Applin @ Sitrus Berry
EVs: 116 HP / 196 Def / 196 SpD
- Sucker Punch
I couldn't have any more ideas because well, lets admit Applin's movepool SUCKS. So, I decided that it will be a staller as it has access to withdraw and recycle. Bulletproof means a decent number of moves won't be able to affect this dude such as Tentacool's and Skrelp's Sludge Bomb, although Sludge Wave is much more common. Withdraw to raise defenses and Attract is to "infatuate" the opposing gender Pokemon. It has to be bulky so max defense and special defense, although Abra will make this dude "get rekt" and you might want to switch to another Pokemon. A good example might be Vullaby, as it is immune to Abra's STAB Psychic and resists Shadow Ball, so it is the perfect teammate for Applin. Another example is Pawniard, as it is a sweeper and has the same advantages like Vullaby too. Just one difference, Vullaby's a staller while Pawniard's a sweeper. Sucker Punch to take damage while stalling when you regained your HP back with the sitrus berry.
Hope you like this moveset :).
