So, being bored of regular OU teams, I decided to make a team to try and prove that the first generation is still the best.
First glance:
Team Building:
I knew how good my Alakazam was as a lead for quickly hitting things hard after using it in standard battling, so I started with that.
Then, I needed a more defensive pokemon, which could support as well. With excellent special defense and support options, Venusaur was in.
I then realised that a physical sweeper was needed, to complement Alakazam. I went with Charizard, both because of its impressive attack and the fact it is an iconic Kanto Pokemon.
Realising Charizard's massive problem with Stealth Rock, I needed a Spinner. I could've used Starmie, but I felt that Blastoise filled the role better to absorb physical attacks as well as Spinning.
I then wanted an element of surprise added into the team. This came in the form of a Specs Dragonite.
I needed something else to finish off. The team lacked pace outside of Alakazam, so I added a Jolteon which could also act as an effective late-game sweeper.
Here is the team broken down:
Spoonbend @ Focus Sash
Synchronize
252 Attack 252 Speed 4 Special Defense
Modest
-Psychic
-Charge Beam
-Shadow Ball
-Focus Blast
This is my attacking lead. I like to get off a charge beam and hopefully get a Special Attack boost, raising his attack to ridiculous levels. The lack of any support moves means I'm not worried about Taunt leads, while the Focus Sash combined with max Speed means that I will always get one attack off, normally at least two.
Synchronize is more useful that inner focus in most cases, except fake out. However, I like to switch out Alakazam if a Fake Out lead such as Ambipom is in, to prevent the focus sash not being used.
Tricerotop@ Leftovers
Overgrow
252 HP 252 Special Defense 4 Defense
Calm
-Sleep Powder
-Leech Seed
-Energy Ball
-Sludge Bomb
This is a solid support option. I first use Sleep Powder, which forces a switch. This leaves me free to use Leech Seed on whatever comes in. Combining with Leftovers replenishes Venusaur's health fairly quickly. The offensive moves are in there for double STAB, with Sludge Bomb the regular attack as it has slightly more power. I believe that Venusaur deals with bulky walls such as Suicune or Cresselia, by having the Leech Seed slowly take their health and get rid of Lefties replenishment.
Rawr@ Lum Berry
Blaze
144 HP 252 Attack 112 Speed
Adamant
-Flare Blitz
-Earthquake
-Dragon Dance
-Roost
Pretty simple really. I bring in Charizard on something that will switch, and take advantage of this using Dragon Dance. Normally I only get one off as they bring in a counter, but I try to get two. Earthquake for powerful physical damage, and Flare Blitz for both that and STAB. I can Roost off the recoil damage from Flare Blitz, as well as eliminating the electric weakness for one turn. Lum Berry gets rid of any annoying paralysis, mostly.
TheOrigin@ Leftovers
Torrent
252 HP 252 Defence 4 Special Attack
Bold
-Rapid Spin
-Toxic
-Protect
-Surf
This works really well with Charizard. As Charizard can't come in with Stealth Rock on the field without losing half of its health, I bring in this before to clear the field. Another advantage of this is to put Toxic onto the opponent, and if I have to stall it with Protect I can. Surf is there for attacking, obviously, as it is the most reliable STAB special attack.
DragoMence@ Choice Specs
Inner Focus
252 Special Attack 252 Speed 4 HP
Timid
-Dragon Pulse
-Thunderbolt
-Fire Blast
-Surf
This is the wildcard of my team. Most people, when they see a Dragonite, will think of Dragon Dance and Outrage, and so will switch to a physical wall. While Dragonite does not have the best Special Attack, Choice Specs boosts this to very good levels. Max Speed is important rather than Special Attack, as the Specs make that high enough anyway, and max Speed means I can outspeed some common counters.
I'm not entirely happy with the moveset, especially with Surf, as I just wasn't sure what to put in. However, it does give good type coverage, and each of the attacks is pretty powerful. Fire Blast over Flamethrower for more power, and Dragon Pulse over Draco Meteor as I don't really want to be switching out after every hit.
Joltace@ Petaya Berry
Volt Absorb
252 Speed 252 Special Attack 4 Special Defense (Not really sure about this as I was traded it)
Timid
-Substitute
-Thunderbolt
-Shadow Ball
-Hidden Power Ice
Bring in on a counter or an electric type move, and start to Substitute until the Petaya is activated. Thunderbolt is standard STAB, HP Ice deals with Dragons and Shadow Ball for Ghosts.
Getting down to the health required with Substitute shouldn't be a problem, as Jolteon will outspeed almost everything.
Thanks for any feedback :) So far I have had 3 wins and 1 loss with this team.
Sorry, I accidentally put this in Other Teams first.
