Yoshi's Big Gay Ambitious Project

[Yoshimitsu]

Okay! For my summer, I'm going to see if I can't train at least one of every final-stage pokemon to use competitively. Gonna go through the pokedex, one at a time, and train each pokemon (possibly two of each pokemon!).

So, starting with Venusaur, we already have two movesets. The first:

Physical Venusaur
Venusaur@Zoom Lens/Black Sludge
Brave(Zoom Lens)/Adamant(Black Sludge)

252 Atk/Sp. Def

Power Whip
EQ
Swords Dance
Sleep Power

Basic set up would be Sleep Powder -> Swords Dance -> EQ or Power Whip. Gets walled by flying, but there's not a lot that can be done about that. Leaning towards Adamant/Black Sludge, to keep Venusaur in the battle for longer. The Zoom Lens is to help Power Whip and Sleep Powder actually hit, making up for their lower accuracies.
Put on hold temporarily, until I get around to grabbing something that can breed Power Whip on to it.

Special Venusaur
Venusaur@Black Sludge
Quiet

252 Sp. Atk/Sp. Def

Energy Ball
Sludge Bomb
EQ
Sleep Powder

Again, Sleep Powder to start. Energy Ball and Sludge Bomb for STAB and EQ for Steel, Fire and Heatran pokemon. Still gets walled by a lot, but I didn't expect Venusaur not to. Black Sludge is just to help Venusaur stay alive for that extra turn, where possible.

Special Charizard@???
Modest/Timid

252 Sp. Atk/Spd

Flamethrower/Heat Wave
Dragon Pulse
Air Slash
Solar Beam/Hidden Power?

Hidden power depends on what time. Otherwise, Solar Beam for a Sunny Day team. Flamethrower/Heat Wave and Air Slash for Stab and Dragon Pulse for a strong attack that helps with coverage. Modest for the extra fire power, or Timid for the extra speed to out-speed those pesky fast pokemon.

Physical 'zard
Charizard@Focus Sash
Adamant

Flare Blitz/Fire Punch
EQ
Dragon Claw
Dragon Dance

Dragon Dance to boost Speed and Attack, with the Focus Sash to hopefully allow at least one DD. Flare Blitz has the raw power, but might fall down due to Charizard's lackluster defenses and heavy weakness to rock. Fire Punch lacks some power, but STAB still takes it up to about 100-110 base power, boosted by DD. Dragon Claw for help with coverage. EQ has raw power and helps deal with rock pokemon.

For Venusaur, if you can get HP Fire, use it over Earthquake - it'll likely be the more reliable option, but Earthquake will do fine since Venusaur lacks anything better outside of Hidden Power. You can put the Sp.Defense EVs into HP to get an even blend of bulk across the defenses, but it's not extremely important. Also, Leaf Storm tends to be a more popular choice over Energy Ball thanks to the extra power earning surprise OHKOs against certain foes that Energy Ball can't destroy that quickly.

Things are a bit more complex for Charizard since he has an ever-perpetual little issue that clips his wings: Stealth Rock. You will need to learn to deal with this to be successful with 'Zard, and luckily, not only can this be done quite easily, but 'Zard can even turn the entry hazard to his advantage with a combination of Blaze and Substitute - if your HP is divisible by four, then Stealth Rock damage + Substitute = Blaze for you with 25% HP to spare, which can easily turn the tables at the end of the game.

As for moves, Fire Blast is probably the best pick for Fire STAB, but Flamethrower works if you don't trust your luck. The best Hidden Power is Electric, but with Substitute already on your set any combination of Dragon Pulse, Focus Blast and Air Slash works too.

The most popular physical Charizard is the Belly Drummer - this time, if your HP is NOT divisible by four, Stealth Rock + Belly Drum will drop you to 1% HP and maximize your Attack as well as putting you into Blaze. Fire Punch is the STAB of the day for this set, combined with Earthquake and whatever else takes your fancy for the third slot. This set is quite hard to pull off and is very vulnerable to priority revenge-killers, but if your opponent lacks anything that can hit you first (Salac Berry is a popular item for both 'Zard sets) then you're free to sweep away.
