I just decided to post my Slaking that I used to use against Garchomp back in the day. I used to use this guy along with a dual-screen support, which made me usually kill at least one pokemon or two during the whole game.
Slaking @ Choice Band
Ability: Truant
EVs: 92 HP/164 Atk/252 Def
Adamant nature (+Atk, -SAtk)
- Giga Impact/Double Edge
- Ice Punch
- Fire Punch
- Earthquake/Sucker Punch/Thunder Punch
This Slaking can deal some massive damage during its short time every now and then as it is switched in and out of the game. This Slaking set can also do something others cannot, with ice punch, it can OHKO a YacheChomp (meh I thought this was interesting and it did pretty well back when I used this guy against Garchomps with my dual-screen support) With reflect, this Slaking can actually take a hit by the SD’d Garchomp’s outrage (with life orb even) and then another (since it is slower) before OHKO’ing him with an Ice Punch. Also, it is capable of doing the same against SDYache Garchomp. YES! Even if he has the yache berry, this Slaking CAN OHKO him with an ice punch as shown below in calculation 1. Furthermore, as shown below, calculation 2 tells us that even the outrage from SD’d Garchomp with the life orb will not even two hit KO this Slaking.
Other Garchomp variants, such as CBChomp, ScarfChomp will be mentioned but these will not be nearly as effective against this Slaking since SDLO is stronger than those two while fast enough to outrun Slaking anyways so Scarf wouldn’t play a major role against Slaking compared to the SDChomp. However, this slaking will have a hard time against ChainChomp as his special defense is frail but then again who can wall all variants of Salamence? This Slaking with the reflect support (or Dual-Screen Support) will be a living nightmare to Garchomps.
The Even attack EV along with adamant is absolutely needed to OHKO YacheChomp. Also, with the high attack and Double Edge, it can even OHKO 0HP/252Def Bold Blissey (another option: Giga Impact). With the high HP and mediocre defense, it can also survive many physical attacks.
As shown below in the calculations, Slaking is able to OHKO many while 2HKO’ing the rest. The pokemons that Slaking cannot OHKO but 2HKO (like Dusknoir, Bronzong, and Skarmory), while not OHKO’d, will not give Slaking major problems as they are walls, which should be dealt with other pokemons such as the wall breakers.
Defensively, while his special side is weak, with his normal typing (except for fighting type moves/pokemons, none is super effective against Slaking) and great HP with defense stats, he will survive numerous attacks and fights, even with his ability truant. I have calculated the damage dealt by the major sweepers of the current metagame from calculations 12 to so on below.
Pokemons such as Lucario, Infernape, Salamence, and Scizor with Superpower will cause problems for Slaking without reflect support (OHKO him). For the most part, however, Slaking can be an incredibly devastating in the right hands as a pokemon who goes in cause massive damage and comes in again. Truant may seem an monstrous hinderance but in the current metagame where players constantly switch pokemons in and out, this should not be such a big problem especially with his high HP and defensive mechanism.
