Last year, I posted a team utilizing a Slaking http://www.smogon.com/forums/showthread.php?t=65471&highlight=Slaking. I have went through many revisions, learning some lessons along the way. One of the lessons learned was that I can improve my chances of winning by having a fail-proof Rotom-H / Gengar counter. My latest revision revolved around dispatching Rotom-H and Gengar for optimizing Slaking's damage output and minimize damage done by these ghosts. There are many risks in having Slaking, which I tried my best to alleviate with the current team. Despite all of my efforts, it has been a rough trial in making this team to be consistently good, so I finally decided to post this team for some awesome advice.
TEAM AT A GLANCE
Metagross @ Choice Scarf
Clear Body - 252 Atk/4 Def/252 Spd
Jolly nature (+Spd, -SAtk)
- Meteor Mash
- Pursuit
- Stealth Rock
- Thunderpunch
Gengar buster. I previously had Iron Ball + Trick Lead, but my team is very slow and so I decided to re-assign Metagross the revenge-killing role. Meteor Mash + Pursuit terrorize Gengar and I added SR on Meta because I couldn't fit on any other monsters. Thunderpunch allows Metagross to revenge LO Starmie and Gyarados or to dent Suicune enough for Slaking / Celebi to finish off. I wish I could stick Zen Headbutt or EQ somewhere to revenge kill Infernape and Lucario, but my team has more trouble with the Waters.
Gyarados (F) @ Leftovers
Intimidate - 248 HP/184 Def/76 SDef
Impish nature (+Def, -SAtk)
- Avalanche
- Waterfall
- Sleep Talk
- Rest
Core defense of this team. Committed defense investment is essential for sponging fiery hits from Heatran and Infernape as well as weakening blows from Machamp and Lucario. Also a great switch-in to Scizor and Flygon's U-turn. Complements Metagross' weakness very well, coming in on Salamence's EQ / Fire Blast. It can then absorb a Draco Meteor or an Outrage to kill the dragon with an Avalanche.
I had Taunt over Rest to prevent set-up, and worked surprisingly well in conjunction with Avalanche, but with SR up Gyarados doesn't last long without Rest. Now it has a tendency of becoming a set-up fodder, though :/
Hariyama (M) @ Leftovers
Thick Fat - 136 HP/252 Def/120 SDef
Impish nature (+Def, -SAtk)
- Force Palm
- Close Combat
- Ice Punch
- Payback
With ghosts ideally removed, a Slaking + Fighting Type should reak havoc. I wanted a wall-busting Fighting type here, but ended up taking a defensive approach for a solid Tyranitar counter and more. Additionally, Hariyama, provides extra Infernape protection if Gyarados bites the dust; none of the moves can 2HKO. Close Combat, Ice Punch, and Payback for solid hard-hitting coverage. Force Palm on the switch or stalling mons to potentially turn the table.
Hariyama has been pulling its weight, impressing me with its defensive capabilities. However, at times the lack of ATK investment shows when it has trouble dispatching Swamperts, Forretresses and the like. If it wasn't for the extra Infernape protection, I may opt for a Breloom for the much-needed firepower.
Slaking (F) @ Choice Band
Truant - 252 Atk/4 Def/252 Spd
Adamant nature (+Atk, -SAtk)
- Earthquake
- Fire Punch
- Return
- Sucker Punch
Star of the team. Not much to say, except that it is a double-edged sword that brings devastation to the opponent's team, but then provides a breathing room for the opponent to retaliate. Thus by necessity, Slaking teams tend to become defensive.
Tyranitar (M) @ Lum Berry
Sand Stream - 252 HP/56 Atk/24 Spd/176 SAtk
Quiet nature (+SAtk, -Spd)
- Dark Pulse
- Fire Blast
- Pursuit
- Stone Edge
Tyranitar has been consistently sniping Rotom-H. Lum provides Wisp protection. While Rotom-H attempts to burn Tyranitar, it OHKOs Rotom-H with a Dark Pulse + Pursuit. Although, Superpower would hit Heatran, opposing Tyranitars, and Blisseys for SE damage, I decided to go with Stone Edge for a solid STAB. The special defense boost is much appreciated, allowing Tyra to survive Starmie's special hits as well as providing another monster to take Heatran's Fire moves.
Celebi @ Leftovers
Natural Cure - 252 HP/116 Def/140 Spd
Timid nature (+Spd, -Atk)
- Grass Knot
- Recover
- Hidden Power [Fire]
- Thunder Wave
Celebi is an essential core defense of this team, like Gyarados, providing me a 100% counter to Breloom that plagues Slaking Team. Unfortunately, Celebi is a magnet for Heatran and Infernape, which is why in this particular revision of the team I have incorporated Hariyama and Tyranitar that can survive hits from either one.
Initially it was a Bold >308 Defense celery, but I have decided to give it enough Speed to outrun LO Suicune and Specs Heatran, both monsters that can sweep this team if Slaking is out. This way at least Celebi can paralyze them and hinder their sweeping potential. As an added bonus of extra Speed investment was that Celebi can now revenge Adamant Lucario. The considerably low defense EVs means greater reliance of Gyarados' Intimidate to dampen blows from Gyarados, Machamp, Lucario, and Outrage Dragons.
So this is my Slaking Team. My biggest problem right now is stall. I used to have Breloom, which would use Toxic Spikes against the opponent with Posion Heal, and had Spore and colossal brute force to break walls (I specifically used Spore, Mach Punch, Stone-Edge, and Swords Dance @ LO). If you have suggestions to help me overcome the opposing team's defense so that Slaking could rip the team apart, I will love you.
