Warning! Massive hail storm is coming!
This is my second attemp to build hail team. I make my team rather offensive team than stall or defensive team which is majority of hail user do. I think i cover many of threat except very popular gengar but i think my team would have problem. Moreover, my team doesn't have good lead.
Machamp @leftover
Ability: No Guard
Nature: Adamant
EV's: 252 HP / 252 Atk / 6 Spe
-Dynamic Punch
-Stone Edge
-Rest
-Sleep Talk
Role:
Solid Tyranitar counter which my team desperately need. He resist all of Tyranitar's STAB attack and have neutrality on all other his attack. Dynamic Punch is very good STAB attack when combined with his trait, no guard, and fear off Weavile, Tyranitar who otherwise killing team very easily. Stone Edge is for taking down Gengar and flier especially Gyarados. Rest+Sleep Talk provide fine status absorber and sleep talker.
Why did you use RestTalk Machamp over Hariyama
-better attack and his trait no guard which completely negate horrible accuracy of stone edge
-status absorber and sleep talker
-my team is not a stall hail team
-Heatran and tentacruel already give fire and ice coverage
-My team is gengar weak and miss of stone edge is deadly
(look like a bird....)
Abomasnow @Choice Scarf
Ability: Snow Warning
Nature: Hasty
EV's: 252 Atk / 6 SpA / 252 Spe
-Blizzard
-Wood Hammer
-Earthquake
-Focus Punch
Role:
Mixed attacking Yeti with Choice Scarf. Yes, Abomasnow does have crappy speed and average stat overall but with help of Choice Scarf and his STAB 120 BP he can nullify that problem. Moreover, this Yeti more suit to my offensive hail team than any other set of Abomasnow. I think Sword Dance set is crappy because of Abomasnow's frailness and crappy speed and Choice Band set and Choice Spec set don't abuse his good attack move overall. Of course, this guys problem is it need to switch out a lot. However, Tentacruel spin away hazardous Stealth Rock and make this guy ramapage more against other team.
Why did you use Abomasnow
-This is hail team
-Counter Water Type Poke
Zapdos @Leftover
Ability: Pressure
Nature: Bold
EV's: 252 HP / 220 Def / 36 Spe
-Thunderbolt
-Hidden Power Ice
-Roost
-Light Screen/ Refelct
Role:
Defensive Zapdos here. He can dish out the damage of Heracross, Gyarados, Salamence, Metagross fairly nicely. He is fairly nice wall when count the fact that he have only two weakness which is ice and rock (Pretty common attack in OU though) I don't know what move to use in fourth slot though. Light Screen will helps team defensive side but Reflect will help out the fact that Zapdos is only pokemon that stops Fighter.
Why do you use Zapdos
-Good Team Player
-Physical Wall
-Counter heracross, Gyarados, Salamence, Metagross
Tentacruel @Leftover
Ability: Liquid Ooze
Nature: Calm
EV's: 204 HP / 96 SpA / 172 SpD / 36 Spe
-Surf
-Blizzard
-Rapid Spin
-Toxic Spike
Role:
Tentacruel is one of pokemon that greatly boosted in D/P. He jump from UU to OU. He safely counter dangerous foe like Infernape and absorb special attack crazy with his impressive special defense (HP is not impressive though) Rapid Spin is always welcome on hail team since it cleans out dangerous stealth rock. Toxic Spike to make Mamoswine sweep much easier.
Why do you use Tentacruel??
-Rapid Spin
-Infernape Counter
-Special Wall
-Abuse improved Blizzard
-Absorb Toxic Spike without harmed by it
Mamoswine @Life Orb
Ability: Snow Cloak
Nature: Naughty
EV's: 252 Atk / 20 SpA / 236 Spe
-Earthquake
-Ice Shard
-Blizzard
-Stone Edge
Role:
Mixed Sweeper. STAB Blizzard 2HKO enemy Skarmory, Weezing. OHKO enemy ngrowth, Gliscor, Donphan and take a very large chunk out of Hippowdon.
Why do you use Mamoswine??
-Physical Sweeping
-Dragon Killer
-Abomasnow's snow warning triggers Mamoswine's snow cloak and increase evasion rate
Heatran @Choice Scarf
Ability: Flash Fire
Nature: Modest
EV's: 40 HP / 252 SpA / 216 Spe
-Hidden Power Ice
-Fire Blast
-Earth Power
-Explosion
Role:
Special Sweeper, Azelf counter, revenge killer, and fire absorber. STAB Fire Blast OHKO Azelf almost always and if he get sun boost or flash fire boost it spell death to anything that doesn't resist fire. Earth Power is for other heatran, tyranitar, and rhyinferior (I know correct name but.) Explosion takes out blissey.
Why do you use Heatran?
-Ice and Fire immunity and resistance
-Special Sweeping
-Counter Azelf
-Provide other handy resistance too except very weak to ground, water, and fighting which my other pokemon resist or immune to
-Revenge Killing is fun
I am too lazy to write threat list and commenting so i am not going to add threat list
