The main strategy with this team is to try and take out any Physical Walls/Gyarados counters so Gyarados can get, and sweep.
Here's the team:
Bronzong@Leftovers
Relaxed
Levitate
252HP/152ATK/96SpDEF
-Earthquake
-Charge Beam
-Stealth Rock
-Hypnosis
Bronzong is quite a good opener, setting up SR. Charge Beam for Gyarados openers.
Porygon-Z@Life Orb
Modest
Adaptability
252SpATK + Speed/4HP
-Tri Attack
-Bolt
-Beam
-Phychic
My main Special Attacker. Quite fast, and Tri Attack packs a powerful punch with Ability,Nature and Item combined with massize Sp.Atk.
Suicune@Leftovers
Bold
Pressure
252HP + DEF/4SpAtk
-Calm Mind
-Roar
-Surf
-Ice Beam
Very nice defensive-wise, and if I can some Calm MInds it can damage the opponents team quite a lot. Roar also helps me find out about my opponents team so I can find out what to take out for Gya sweep.
Salamence@Choice Band
Naughty
Intimidate
252 Atk + Speed/4HP
-Earthquake
-Dragon Claw
-Flamethrower
-Rock Slide
Hold on, CHOICE BAND? That's right, I chose CB for a suprise element, since SpecsMence has become the most common, but unfortunately it doesn't work that well.
Electivire@Expert Belt
Mild
Motor Drive
76HP/180Speed/252SpATK
-Cross Chop
-Thunderbolt
-Flamethrower
-HP [ICE]
Again, going for the suprise element here, but 'Vire is very fragile and slow without Motor Boost, but it can really work quite well if used properly.
Gyarados@Life Orb
Adamant
Intimidate
72HP/252Atk/186Speed
-Earthquake
-Waterfall
-Ice Fang
-Dragon Dance
Please rate my team, it needs to improve...
