Hippowdon
Sand stream, Leftovers, impish
252 hp, 252 defense, 6 attack
-Earthquake
-Steal Rock
-Slack Off
-Ice Fang
This here is my lead. He'll get the sandstorm up, cover things with ice and ground, heal off attacks, and stall opponents. He's a necessity for a sandstorm team. Right off the bat I'll get a sandstorm up, unless I feel like I might get taunted. If that happens, I would go to either darmanitan or sazandora. He can wall off many physical attackers, and Ice fang helps with type coverage
Cradily
Suction cups, leftovers, sassy
252 hp, 252 special defense, 6 attack
-Rest
-Sleep talk
-Rock Slide
-Curse
The classic rest-talk cradily. Curse up for defense, spd is already amazing because of the sandstorm, and rock slide away. He is my special wall. With amazing typing cradily will be very difficult to take down, and is my prime counter to blissey. He can just rest off twaves and seismic tosses while walling thunderbolts and cursing enough to take it down with rock slide. If roopushin switches in, and I have at least 2 curses I should be able to take it down.
Goruugu (http://www.serebii.net/pokedex-bw/623.shtml)
No Guard (makes all moves 100% accurate), Life Orb, Adamant
252 attack, 252 hp, 6 speed
-Dynamic Punch
-Earthquake
-Heavy Bomber (steel attack, higher difference in weight=more damage)
-Shadow Punch
When I saw this pokemon's ability and access to dynamic punch, I fell in love. With No Guard, all attacks on the field will never miss, giving me a 100 power 100 accuracy fighting move that confuses the opponent every time I hit. This makes Goruugu a great Roopushin counter, as he can switch into a drain punch and confuse him with dynamic punch. Earthquake, heavy bomber, and shadow punch are just for type coverage and I am fine with changing them. This poke is by far my favorite of fifth gen, and hopefully I will use it well.
Tentacreul
Liquid Ooze, Black Sludge, calm
252 special defense, 252 hp, 6 special attack
-Toxic Spikes
-Surf
-Rapid Spin
-Sludgebomb
Basic tentacreul, nothing special here. His job is to spin away my entry hazards and start setting up his own toxic spikes. Tentacreul gives me that surf/sludge bomb initiative to be super effective against rock and grass, which are 2 large weaknesses to my team. Also, toxic spikes will let hippowdon and cradily stall more effectively
Terrakoin (http://www.serebii.net/pokedex-bw/639.shtml)
Heart of Justice, Leftovers, Jolly
252 attack, 252 speed, 6 hp
-Close Combat
-Stone Edge
-Swords Dance
-X-Scissor
Yet another amazing pokemon. With base 108 speed and jolly nature, he will outspeed a lot. Also, under a swords dance, 129 base attack, and those moves, this thing will be a beast. The sandstorm will also gives this thing more special defense as it is Rock-Fighting, and will be my physical sweeper.
Sazandora (http://www.serebii.net/pokedex-bw/635.shtml)
Levitate, choice specs, Modest
252 special attack, 252 speed, 6 hp
-Draco Meteor
-Overheat
-Surf
-Dark Pulse
There wasn't really much reason I put this guy in here, other than the fact that he is awesome. He's got good coverage and decent specal attack and speed. He can switch in on someone using earthquake, and hit it back with a specs hit coming from that amazing type coverage. He makes for a good revenge killer and a possible late game sweeper. It seems like this will be a pretty uncommon poke in 5th gen, so I could get some surprises out of people.
