Hi Kusanagi Dark, very nice team !
Building a sunny team is not so easy, but a well-built sun team can be devastating.
Your team is good, Xatu + Dugtrio combo gives you the best way to avoid entry hazards, and if a tyranitar tries to kill your bird, you can just send out dugtrio and win the weather war.
A lot of sunny teams are weak to dragons, especially latios, and scizor it's a good choice to kill it. A lot of latioses doesn't have hp fire, and even a specs surf can't do anything under the sun.
If you want to use Victreebel as a rkiller, you can just use Venusaur with HP Ice and Sleep powder instead of it. It's quite better, and put on sleep a pokemon is always a good thing, especially when you can't take out the opponent. Venusaur can take an earth power from Landorus, Victreebel can't. Venusaur has more speed than Victreebel, and it can outspeed scarftios. The only reason to use victreebel instead of venusaur is the possibility to use the flamebeam coverage (weatherball + hp ice), and this thing is good, but the fire move can be useful against Jirachi, which is not a problem for your team, lol. If you try to use it against scizor, just prepare to take this damage: 394 Atk VS 166 Def and 301 HP (40 Base Power): 231 - 272 (76.74% - 90.36%)
Venusaur (M) @ Life Orb
EVs: 72 HP / 8 Def / 252 SAtk / 176 Spd
Timid Nature (+Spd, -Atk)
- Sleep Powder
- Giga Drain
- Hidden Power [Ice]
- Growth / Sludge Bomb
I suggest you to use this Venusaur instead of Victreebel
, it's more bulky and if you want to use it as a sweeper you can overcome steel types with Sleep Powder (but I guess that a steel type can be trapped by Dugtrio, right?). Sludge Bomb it's a good stab, if you want to rkill stuff and deal a good damage generally.
Another thing I can suggest you is to change the spread of Ninetales
, try this: EVs: 248 HP / 212 SDef / 48 Spd
with Calm nature
, it allows you to take scalds and water moves in general better, which is important if you don't want to get someone burned.
Luvdisc'd, GJ and GL :)
