OK first off...Hi. Second, its time to see what you got...
I agree with Marzipans comment for Ninetales. Defensive Ninetales is fine but not with full SpAtk EV's. I think you may enjoy this better...
Ninetales @ Leftovers
EVs: 252 SDef / 126 HP / 4 SAtk / 126 Def
This set is tried and tested but feel free to do what ya like with it.
(Just realised I kept spelling Ninetales wrong!)
Ok now your Bellosom has gotta go. You need a Rain/fire counter, really badly. SlipperyDevil taught me this...
Kingdra @ Dragon Gem/Water Gem
Trait: Swift Swim
EVs: 252 Spd / 252 Atk / 4 SAtk
- Dragon Dance
- Ice Beam
Swift swim works well if rain as been used and Gemed Outrage/Waterfall blasts opponents. Its 4x resistance to fire helps on a switch. This works.
OK good choice; Venusaur Bad choice: Moveset + Item
Sun sweep Venu can be excellent. Notice the "can". You have two grass type moves. En reference to Marzipans set Giga Drain rather than solarbeam,its doesn't have to charge if someone sets up weather,so without sun so its safer. Also it acts as recovery so you can deal damage instead of Synthesis healing, allowing more room for attacking moves. This is something I often use...
Venusaur @ Life Orb/black sludge
EVs: 252 Spd / 252 SAtk / 4 Atk
- Giga Drain
- Hidden Power [Dark]
- Leech Seed
Dark you say? Don't like Psychic types? Thought not. Leech seed/giga drain recovers from life orb if that was your choice. Dunno if this will help but oh well give it a go.
Arcanine is not as common in sun as I thought it would be. I and I don't know why not. its pretty good. Infernape is a very good option though so I devised a set for both so you can choose...
Arcanine @ Leftovers
EVs: 252 Atk / 252 HP / 4 SDef
- Flare Blitz
- Wild Charge
- Morning Sun
Infernape @ Payapa Berry/life orb
Trait: Iron Fist
EVs: 252 Spd / 252 Atk / 4 SDef
- Fire Punch
- Mach Punch
Tell me if this helps so I can use them...joke both are tested.
OK Jumpluff. Wait, Jumpluff? Well...I suppose sun jump can stall for a bit...but use Bliss from before. Its better. Even in sun.
Sceptile is a good pokemon but you need a sand counter pokemon. Ah! Garchomp! OK sand veil is not aloud but it can use rough skin. Aqua tail deals with water types and and various dragon moves deal with dragonite. Too bad it lacks Ice fang. But it would probably be overpowered.
Garchomp @ Dragon Gem
Trait: Rough Skin
EVs: 252 Spd / 252 Atk / 4 HP
- Fire Fang
- Swords Dance
Sweeper Garchomp. WARNING DO NOT APPROACH WITHOUT CAUTION!!
EDIT: I thought of another choice you could try. The swnine of Mamo.
Mamoswine (M) @ Choice Band/Choice Scarf
Trait: Thick Fat
EVs: 4 HP / 252 Atk / 252 Spd
Adamant Nature (+Atk, -SAtk)
Dragon/ground killer. Power ice shard beats many a foe inludeing Hippo and Tyran with appear frequently, along with Dragonite and MoxieMence.
Well thats it really. Hope me helped. Sorry no pics this time.
