Still quite new to this but i'm improving hopefully lol.
Any help appreciated
And now for the team.
Tyranitar @ Focus Sash
Ability: Sand Stream
Nature: Careful
EVs: 240 HP, 36 Atk, 48 Def, 184 SpDef
~ Taunt
~ Fire Punch
~ Stone Edge
~ Stealth Rock
My lead to the team i needed something bulky and what can back up my team against my fire weakness and take down annoying metagross leads this is just a great lead and a valuble member of my team plus sandstorm helps tyranitar survive =].
How it helps the team: This is my set up pokemon and starts everything off for the team with stealth rock and backs up my team by taking down most leads as i had a problem against a Metagross lead.
Zapdos @ choice Scarf
Ability: Pressure
Nature: Modest
EVs: 6 HP, 252 Spe, 252 SpA
~ Thunderbolt
~ Heat Wave
~ Roost
~ U-Turn
This is my main answer to major threats in the games as well as my sweeper many people go with timid or bold but i use porygon 2 for salamance so thats not a problem lucario is mixed i get away with it most the time but my flygon can help that so it's weakness is covered just a fantastic pokemon.
How it helps the team: This is my main sweeper and can be an answer to major threats in the game with only 2 super effective types that can hit it this guy can stay around a long time too with roost only helping it's cause just a useful pokemon to any team.
Porygon 2 @ Leftovers
Ability: Bold
Nature: Trace
EVs: 6 Attack, 252 HP, 216 SpDef, 40 SpA
~ Ice Beam
~ Thunderbolt
~ Recover
~ Thunderwave
My bulky pokemon/wall my anwser to garydos and salamance as suggested. With it's good defences it is quite a wall as well being able to take huge hits of salamance and survive is a testament to it in itself.
How it helps the team: Well it's a duck so that's all you need to know lol but this guy can take major hits off salamance and then kill it which helps my zapdos as it can struggle for speed sometimes so this is my back up also can take down garydos which can prove a problem.
Scizor @ Choice Band
Ability: Technician
Nature: Adamant
EVs: 252 Attack, 252 Speed, 6 HP
~ Pursuit
~ Bullet Punch
~ Superpower
~ U-Turn
Another physical sweeper and also a scouter people get scared of this and try to kill it as soon as making them switch this is when i u-turn out and see what they have bullet punch is amazing and put finishing touches to teams when i'm late game works well with lucarios extremespeed like brothers and helps me take down tyranitar.
How it helps the team: This pokemon is just awesome can destroy teams on it's own this lures out other pokemon which i can take out making it safe for my Scizor come in to have fun makes my 2nd physical pokemon and a greta addition to my team.
Gengar @ Choice Specs
Ability: Levitate
Nature: Timid
EVs: 252 Speed, 252 Sp.Attack, 6 Def
~ Hypnosis
~ Shadow Ball
~ Thunderbolt
~ Focus Blast
The revenge killer to take out major threats in the game this was to replace frosslass as it was much too fragile and abit slower than i need so i changed it for the boss ghost. =]
How it helps the team: My revenge killer does what it says in it's title gets me back in the game if something falls my main answer to tyranitar with focus blast can take down other ghosts too put to sleep pokemon trying to sweep my team then switch thunderbolt filler but useful as coverage.
Lucario @ Life Orb
Ability: Inner focus
Nature: Jolly
EVs: 4 Def, 252 Atk, 252 Spe
~ Swords Dance
~ Close Combat
~ ExtremeSpeed
~ Ice Punch
Physical sweeper originally my Flygon but it wasn't hitting hard enough so i have chosen Lucario to also help with my ice weakness that tore through my team damn ice shard but not a problem no more thanks to this beauty =]
How it helps my team: It's moves have great coverage just a strong pokemon really i was lacking a physical attacker and this pokemon just seemed right backs up my togekiss and zapdos helpful against Ice types that i struggled against before and an all round good pokemon.
My team seems weavile weak anyone got a suggestion to cover myself against ice any help appreciated and thankyou.
