M-Venusaur with Rotom-W has been stated a good few times, but it seems to be paired with mostly bulky fire types like Heatran or Entei or the like. While this makes plenty of sense, and they don't have the best synergy without some 'linking' Pokemon, I have an alternative proposal:
Rotom-W @ Leftovers/Chesto Berry
Ability: Levitate
EVs: 232 HP/56 SpA/220 Spe
Modest Nature
- Volt Switch
- Hydro Pump
- Will-O-Wisp
- Pain Split/Rest
(Mega) Venusaur @ Venusaurite
Ability: (Thick Fat) Chlorophyll
EVs: 248 HP/252 SpA/8 SpD
Modest Nature
- Giga Drain
- Synthesis
- Sludge Bomb
- Sleep Powder
Scizor @ Choice Band/Life Orb
Ability: Technician
EVs: 248 HP/252 Atk/8 SpD
Adamant Nature
- Bullet Punch
- U-Turn
- Pursuit/Swords Dance
- Brick Break/Roost (Brick Break for Superpower in Pokebank OU)
(Roost for LO set, SD optional for LO set.)
Talonflame @ Choice Band/Life Orb
Ability: Gale Wings
EVs: 124 HP/252 Atk/132 Spe
Adamant Nature
- Brave Bird
- Flare Blitz
- U-Turn/Swords Dance
- Steel Wing/Tailwind/Roost
(Tailwind can work on either set, Roost optional for LO set, SD optional for LO set.)
Since there's an inherent downside to using more slots in a team to create a core, I was trying to see how many overlapping 'cores' I could fit within four. There's a FWG core (Talonflame isn't an ideal bulky fire, of course), a voltturn core (either Scizor or Talonflame, perhaps both, especially if lacking item clause), and a slew of resistances, while allowing all of them to hit hard, spread status, hit with priority-- I was trying to see what kind of 'balanced' core I could fit together.
Scizor has always worked well with Rotom-W in the past, Rotom tanking the fire attacks Scizor so fears while Scizor 4x resists grass like Venusaur and punishes the likes of Celebi with a combination of U-turn and Pursuit. All the while, voltturn keeps momentum. Scizor works moderately well with Venusaur as well, resisting the psychic attacks that Rotom only sports a neutrality to while remaining neutral to flying. U-Turn and Pursuit, again, helps immensely.
Talonflame, meanwhile, sports less bulk than the others, but can still take unboosted fire or fightings moves, and it decimates the average Ferrothorn. This coverage is invaluable, and the extra ground immunity is certainly welcome, as are the additional fire and fighting resistances. Other options like tailwind, u-turn, roost, or swords dance can provide further momentum, retain bulk, or punish switches.
I'm sure that these aren't the most synergetic setups, but it's a simple setup (throw some bulk and damage on everyone) that's pretty flexible. Voltturns keep any but Venusaur from being trapped (which it can oft handle with a sleep powder on the switch)... but I haven't a clue if Rotom+Scizor is sufficient to stop your average dragon. I'm sure there's plenty of things I've overlooked, so by all means, advise-away. New here, but I just wanted my first post to at least be an attempt to contribute some meaningful discussion. ^^"
