Need help against Dr. Sigmund ><

[Poopbricks]

So I basically hit a roadblock after defeating the ice gym, when I went up against Doctor Sigmund, and honestly, I didn't know denying the fight with him earlier would force one now D: my team really has nothing for his, so what should I catch/do to beat him?

My team:

Level 47 Staraptor (Reckless)

-Aerial Ace

-Quick Attack

-Close Combat

-Take Down

Level 50 Blaziken (Speed Boost)

-Blaze Kick

-Double Kick

-Bulk Up

-Brave Bird

Level 47 Luxray (Intimidate)

-Spark

-Charge
-Leer

-Crunch

Level 47 Azumarill (Huge Power)

-Aqua Tail

-Superpower

-Aqua Ring

-Double Edge

Level 47 Gardevoir (Trace)

-Psychic

-Shadow Ball

-Magical Leaf

-Calm Mind

...and a level 18 Kricketune as a HM slave

My team's pretty electric weak but so far I've been trying leer-crunch on my Luxray since it takes neutral damage from his team, but eventually I'll either run out of Crunch PP or Lanturn/Rotom confusion hax me to death. I was thinking of getting a mold breaker excadrill for his levitators, but I realised I can only catch a drillbur after getting the 7th badge :c. Should I get like a gravler or onix, or change up my strat?

Ouch. Try using a few electric resistant pokemon, like quagsire, seismitoad, gastrodon and swampert. Escavalier and Amoongus help a lot too.

Hmm... I might want to try catching two foongus and do some regenerator shenanigans. Though, Electivire has ice/fire punch :s

GRASS-TYPES GRASS-TYPES GRASS-TYPES.

These do so well against Siggy's core, since they resist Electric and most can pack a punch back. Give them a shot.

I used Flygon to rip his team apart with earth power, speaking of witch I need to breed for earthquake.

When he switches in something that can use an ice move, switch out for a different Pokemon. It takes a bit to learn the Pokemon and there moves, but I ended up beating him on my third of fourth try with Flygon.
