I've always been interested in stall but have never tried it out. This is my first attempt and it's been fairly successful, but could use some improvement.
All changes will be bold
Hippowdon (F) @ Leftovers
Trait: Sand Stream
EVs: 252 HP / 252 Def / 4 SDef
Impish Nature (+Def, -SAtk)
- Slack Off
- Stealth Rock
- Roar
- Earthquake
Not to much to say on the moveset and evs as it's pretty standard. I usually lead with her, depending on my prediction for the their lead. In most cases she gets up SR and they bring in a check for her so I switch out and bring her back later for physical walling and phasing. If they lead with a sweeper I'll Roar before setting up SR to prevent any setup She can also takedown a Excadrill if needed, assuming his balloon is popped.
Tyranitar (M) @ Choice Band
Trait: Sand Stream
EVs: 4 HP / 252 Atk / 252 SDef
Adamant Nature (+Atk, -SAtk)
- Crunch
- Fire Punch
- Pursuit
- Superpower
I'm in love with this set, no one expects him to be banded so he catches everyone by surprise. I lead with him against other Tyranitars and Abomasnow, as well as if I predict a poke he's super effective on. The evs are to give him some added bulk and make him hit harder. He can OHKO other Tyranitars, Latias, Latios, Heatran and Reuniclus just to name a few.
Ferrothorn (M) @ Leftovers
Trait: Iron Barbs
EVs: 252 HP / 48 Def / 208 SDef
Relaxed Nature (+Def, -Spd)
- Leech Seed
- Spikes
- Power Whip
- Gyro Ball
I've loved Ferrothorn since the release of B/W. I'm not sure what the evs do for him exactly, but they seem right. His relaxed nature increases his defense and makes Gyro hit for even more. The seed/toxic combo brings down foes very quickly and gives him some recovery on top of lefties. Power whip seems to catch people off guard for whatever reason. If I expect a switch I usually toxic, sometimes seed (like if they have heatran).
Removed Toxic for Spikes when I took out Deoxys-D. Works great and can still wear enemies down without Toxic
Jellicent (M) @ Leftovers
Trait: Water Absorb
EVs: 248 HP / 216 Def / 44 Spd
Bold Nature (+Def, -Atk)
- Scald
- Toxic
- Taunt
- Recover
Everyone knows the Jellithorn combo. Water Absorb allows it to eat shots directed at Tyranitar or Hippowdon, which Politaod always attempts. If I expect a switch I usually Will-O-Wisp. Taunt is useful if I expect a status move or I know they have recovery. I'm not sure about scald over surf, considering I can already burn.
Terrakion @ Choice Scarf
Trait: Justified
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature (+Spe, -SAtk)
- Close Combat
- Stone Edge
- X-Scissor
- Earthquake
Great recommendation by New World Order and a great revenge killer. I went for Sacred Sword over Rock Slide because I see it being more useful, but either would be used much anyway. Him and Tyranitar make great clean ups end game
Gliscor (M) @ Toxic Orb
Trait: Poison Heal
EVs: 252 HP / 184 Def / 72 Spd
Impish Nature (+Def, -SAtk)
- Toxic
- Earthquake
- Fascade
- Protect
My switch in to Excadrill, Ice Fang to pop the balloon, if he stays in then EQ kill him, if not I keep him safe until he gets a chance. I toxic if I expect a switch. Most of the time I protect before I switch out and the almost always use the same move on the next turn, allowing a easy switch in. I see fling as a waste, as it's basically a one time toxic. Ice fang allows him to take down other Gliscors and pop balloons.
The only thing I can think of that gives me trouble is Skarmory on occasion, but Tyranitar usually takes him out, if not Ferrothorn can seed and Jellicent can burn then just outlast him. If he starts using brave bird I switch in Ferro and Iron Barbs mixed with recoil adds up quick. And taunt destroys him.
Something I forgot is Breloom gives me a lot of trouble
