If there's something I really enjoy in pokemon, it is breaking stall teams. Now we all know that with the addition of Mega Sableye, these teams got a huge boost and are increasingly challenging to beat: "traditional" stallbreakers running Taunt are turned into setup fodder, and Mega Sableye grants the user control of the hazard game if the opponent's SR user doesn't threaten it directly. That's why having a SR user that doesn't care about Sableye coming in or that can capitalize on said switch-in has become important. That's why i found Stealth Rock + Magma Storm Heatran to be particularly effective in the current metagame:
Heatran @ Air Balloon / Leftovers
Ability: Flash Fire
EVs: 4 Def / 252 SpA / 252 Spe
Timid Nature
- Magma Storm
- Stealth Rock
- Ancient Power / Taunt / Toxic
- Earth Power / Taunt / Toxic
If the opponent knows that this is your Stealth Rock user, he will most likely try to switch Mega Sableye in to prevent SR from going up, and Magma Storm not only allows Heatran 2HKO it, but also prevents the opponent from saving Mega Sableye for later to recover back the damage (other SR users such as EP Landorus-T can't prevent it from switching out and sticking around), effectively removing the centerpiece of ORAS Stall from the game (assuming the second Magma Storm hits, damn it). After that, you're free to set up SR and start weakening the opponent's team. The choice of the item and of the last two moveslots is up to preference. Leftovers + Taunt + Toxic allows you to bluff a less aggressive set and helps stallbreaking in the traditional way after removing Sableye; on the other hand, Air Balloon + pseudo-edgequake coverage allows Heatran to set up SR more easily against offense, shut down opposing Heatrans, and provide you with a more reliable check to SD Talonflame thanks to Ancient Power, which is something many offensive teams appreciate. Ah, and Magma Storm is a great move against offensive teams, as you can prevent the Heatran switch-in from switching out, allowing you to bring your counter in safely without fearing the double.
If you're paranoid about accuracy you could even run Flamethrower + Magma Storm to KO Sableye reliably after the first Magma Storm hits but it is not advised imo as it is redundant in too many other situations if compared to great tools like taunt / ancientpower ecc.
252 SpA Heatran Magma Storm vs. 252 HP / 4 SpD Mega Sableye: 144-171 (47.3 - 56.2%) -- 82.4% chance to 2HKO (guaranteed with the subsequent 12.5% damage)
EDIT: Fuck XY trapping mechanics (see below). At least, this is still an example of a SR user that threatens Mega Sableye with a 2HKO. Especially if your opponent doesn't know that he can switch out. -__- Magma Storm is still a good move as it prevents your opponent from doubling out after it hits.
Also, bonus tool against sableye stall:
Absol-Mega @ Absolite
Ability: Justified
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Knock Off
- Sucker Punch
- Play Rough
Absol got a great buff with ORAS, as it finally has access to Knock Off + Play Rough on the same set, which is a combination that is only resisted by Klefki, i think. Moreover, it now gains the role of shutting down non-Foul Play Mega Sableye, bouncing back WoW and setting up on it. The SD + Knock Off + Sucker Punch combination is deadly, as Bisharp taught us, and it allows Absol to perform well against offense, in conjunction with its good speed tier. It is also cool because it baits Keldeo and Landorus-T to switch in. Removing the potential Scarf with Knock Off on the switch (and KOing it with the subsequent Play Rough in Keldeo's case) opens up the opportunity for other fast attackers such as Greninja (
pls ban it) to wreak havoc. This guy is extremely underrated right now from my experience.
252 Atk Mega Absol Knock Off (97.5 BP) vs. 0 HP / 4 Def Keldeo: 96-113 (29.7 - 34.9%) -- 12.6% chance to 3HKO
252 Atk Mega Absol Play Rough vs. 0 HP / 4 Def Keldeo: 238-282 (73.6 - 87.3%) -- guaranteed 2HKO
