5th Gen Hail Guide
By JonathanRP
Introduction to Hail
Drizzle, Drought and Sandstorm. At the moment, the current metagame almost completely revolves around these three weather conditions, with the massive offensive threat each of these conditions provides. However, there is one more weather condition available, that being Hail. This guide will help you to understand the mechanics and uses of Hail.
Hail is a weather condition that is activated when either of two conditions are accomplished. The main way to activate Hail is to use a Pokemon with the ability Snow Warning. There are two Pokemon who have this ability, Snover and Abomasnow. Snow Warning causes the weather to change to Hail, which is a permanent effect, assuming that nothing cancels it out, such as another instant weather Pokemon, or the usage of weather move, such as Sunny Day.
Hail deals 6% damage to any Pokemon that is not Ice typed, or that does not have the ability Magic Guard or Overcoat. Hail also grants 20% evasion to any Pokemon with the ability Snow Cloak, and Ice Body heals a Pokemon 1/16 of its max health at the end of every turn. Blizzard also becomes 100% accurate while Hail is active.
Building Your Hail Team
A common misconception (and perhaps one of the reasons that Hail is not as popular as the other weather conditions) is that Hail teams must be mono-ice typed. This is not true. While Ice type Pokemon are immune to hail, having a pure Ice team is basically suicide in the metagame, with the prevalence of insanely powerful fighting-type physical attackers in the current metagame, such as Conkeldurr.. A successful Hail team will have a lot of variety in the typing that is used. One of of the top priorities of anyone constructing a Hail team is to include Pokémon that are able to eliminate other instant weather Pokemon. Abomasnow itself is able to do a decent job of this, as its typing gives it super-effective coverage against three of the four Pokemon with these abilities. Its Grass STAB allows it to hit Tyranitar, Hippowdon and Politoed super-effectivly, while its Ice typing allows it to do more damage to Hippowdon (with Blizzard). Abomasnow is also fortunate enough to have access to Earthquake, and while Earthquake won't be OHKOing Ninetales unless you're running Choice Band, after entry hazards such as Stealth Rock, you have a good shot at OHKOing Ninetales without resorting to a Choice Band.
Abomasnow
The staple of any Hail team. Abomasnow has the misfortune of having 7 weaknesses, which often overshadow the use that it provides. However most of the time, Abomasnow will only be used to provide Hail. Abomasnow has many things going for it though. Abomasnow is graced with access to 2 100% accurate 120 BP STAB moves, those moves being Blizzard and Wood Hammer. Coupled with Abomasnow's decent 92/92 offenses, Abomasnow can cause a dent in most Pokemon, however, you'll generally only be OHKOing Pokemon that are weak to his STAB moves. Abomasnow
has the option of using Swords Dance, but Abomasnow is too weak defensively and too slow to pull a set off successfully.
Defensive Hail
Since Hail is primarily used for Stall, you will want to have a good defensive backing on your team. Sadly, Hail is one of the worst defensive types, boasting a grand total one one resistance, while having four weaknesses. However, there are many Ice type Pokemon that have good bulk that are able to stall out well.
Walrein
Another staple of Hail teams, Walrein, while completely outclassed outside of Hail, is one of the most potent Hail stallers there is. With its ability, Ice Body, Walrein gains 1/16 of its maximum HP at the end of every turn. Adding this together with Leftovers, Walrein is able to put up a Substitute and use Protect, regaining the HP it lost from using Substitute. Combine this with the opponent taking damage from Hail, and the move Toxic, and Walrein can stall out half of the opponent's team.
Possible Set:
Walrein@Leftovers
Ice Body
Surf/Blizzard
Toxic
Protect
Substitute
Bold Nature
4 HP/ 252 Def/ 252 SpDef
Rotom-F
Rotom-F was a great Pokemon to use in 4th generation, and it has become even more useful in 5th gen. The Rotom forms now gain the type of their special move as a secondary typing, giving Rotom-F the godsend in typing, STAB on the infamous BoltBeam combo, as well as immunity to hail damage.
A STAB Blizzard at 100% accuracy coming off of a base 105 special attack stat hurts, and Rotom-H even has great defenses to boot. A decent speed allows it to outspeed all unboosted weather summoning Pokemon, with the exception of Ninetales. Blizzard can OHKO Hippowdon, and Rotom-F can cripple Tyranitar with Will-O-Wisp. Politoed takes massive damage from Thunderbolt.
Possible Set:
Rotom-F@Leftovers
Blizzard
Thunderbolt
Will-O-Wisp
Shadow Ball/Hidden Power Fighting
Timid Nature
4 hp / 252 SpA /252 Spe
Articuno
While Articuno's movepool hasn't seen any improvements to mention, Articuno gets the ability Snow Cloak from the Dream World. Couple that with Articuno's fantastic bulk, and you get a fantastic staller. A combination of Substitute, Roost, Blizzard and Toxic can completely wear down your opponent's team.
Rankurusu:
