I'm looking for a good Sun Setter for my Platinum Battle Tower team, the others are:
Heatran @ Shuca Berry
Bold nature (can't really change this)
-Fire Blast
-Solarbeam
-Earth Power
-Dragon Pulse
Heatran is the nuke of the team, Fire Blast in the sun should annihilate almost anything that doesn't resist it. Good typing, great stats, great ability. Solarbeam hits most water types like Swampert and Slowking, Earth Power hits other Fire types, and Dragon Pulse hits Dragons.
Zapdos @ Leftovers
Docile nature
-Thunderbolt
-Heat Wave
-Hidden Power Ice (Base Power 61)
-Roost
Zapdos gets a boosted Heat Wave, and has good defensive synergy with Heatran. Hidden Power Ice covers Garchomp, Salamence, Flygon, Dragonite, Altaria, and Lati twins. Heat Wave covers Lucario and Scizor, and just hits hard. Thunderbolt is STAB and covers Charizard and Gyarados, among others.
As a sun setter I'm doubting between several options:
Lucario @ Heat Rock
Adamant/Jolly nature
Ability: Inner Focus
-Sunny Day
-Close Combat
-Extremespeed
-Blaze Kick
Lucario covers Tyranitar, Thick Fat Snorlax, and Blissey well (which my other pokémon have trouble with), but it shares a ground and fighting weakness with Heatran. It also requires Blaziken to breed both Blaze Kick and Sunny Day onto it (Leafeon to Blaziken to Lucario, with Leafeon providing Sunny Day).
Dragonite @ Heat Rock
Adamant/Jolly Nature
Ability: Inner Focus
-Sunny Day
-Superpower
-Extremespeed
-Fire Punch / Dragon Claw
Dragonite also covers Tyranitar, Snorlax, and Blissey with Superpower, as well as resisting fighting and ground. But it shares Ice and Rock weaknesses with Zapdos, and Sunny Day conflicts as a bred move with Extremespeed, so this set needs TM11 (unlike all the other options listed which can get Sunny Day by breeding).
Hariyama @ Heat Rock
Adamant nature
Ability: Thick Fat
-Sunny Day
-Close Combat
-Stone Edge
-Fire Punch / Earthquake
Hariyama has bulk to set up sun, and it doesn't share any weaknesses with either Zapdos nor Heatran, but it's fairly slow.
Scizor @ Heat Rock
Adamant nature
Ability: Technician
-Sunny Day
-U-turn
-Superpower
-Bullet Punch
Scizor doesn't share any weaknesses either, and hits really hard, but it can't set up sun against fire types and it doesn't benefit from sun itself.
Gallade @ Heat Rock
Jolly nature
-Sunny Day
-Close Combat
-Psycho Cut
-Leaf Blade / Fire Punch / Stone Edge
Gallade doesn't share any weaknesses with Heatran or Zapdos, covers Tyranitar, Blissey, and Snorlax with STAB Close Combat, but it has terrible physical defence.
Garchomp @ Heat Rock
Adamant / Jolly nature
-Sunny Day
-Earthquake
-Dragon Claw
-Fire Blast / Draco Meteor / Fire Fang
Garchomp is Garchomp, fast, hard-hitting, and fairly bulky, but it shares a nasty ice weakness with Zapdos, and it lacks a good fighting move to cover Blissey and Snorlax.
Infernape @ Heat Rock
Adamant / Jolly nature
-Sunny Day
-Close Combat
-Flare Blitz
-Stone Edge
Infernape shares a ground weakness with Heatran, but it resists fire and isn't weak to rock. It also gets STAB fighting moves and benefits from the sun. The main drawback is that Infernape is kind of fragile.
