Is this a good team for the Battle Tree in Sun / Moon?

Question

Lucario @ Lucarionite
252 EV's SpAtk + Sp
Ability: Steadfast

-Flash Cannon
-Vacuum Wave
-Aura Sphere
-Nasty Plot

Dragonite @ Choice Band
252 EV's Atk + Sp
Ability: Multiscale

-Outrage
-Extreme Speed
-Earthquake
-Iron Head

Thundurus @ Electrium Z
252 EV's SpAtk + Sp
Ability: Volt Absorb

-Thunderbolt
-Hidden Power (Ice)
-Sludge Wave
-Agility

Please let me know I want to know if you guys come up with any tips since Mega Kangaskhan got nerfed and not really usable anymore.

Pretty good team since dragonite is a tank and if possible teach drogonite ice punch in case u meet any grass types, lucario is all set I think a nasty plot of two can take out a lot of Pokemon, and thunderus is all good I think a flying type move would be helpful

First, you should tell us the natures. Second, mega Kangaskhan is still very overpowered, but I wouldn't recommend it for this team because mega Lucario is better.

---

Thanks for your feedback, since I'm not a nature expert, I'll leave it to you to decide if these are good natures:
(Mega) Lucario: Timid
Dragonite: Adamant
Thundurus (Therian form): Modest

Thanks for your feedback, natures of the Pokémons are added as comment on the question :)

Dragonite appreciated earthquake and iron head more than it appreciates ice punch because it needs those two moves for steel and fairy, while outrage already hits grass pretty hard.

Replace Lucario with Blaziken for speed boost and better offensive typing. Give Dragonite 252 HP/252 Atk/4 Def adamant to take hits better, and replace iron head with fire punch to cover steel and ice better. Give Thundurus timid nature to outspeed more stuff and replace agility with nasty plot to break more defensive Pokemon.

I actually have the same core of Dragonite and Mega Lucario on one of my battle tree teams. I use a different set for each and I have Toxapex for my third 'mon but I still think it's a great team!
