I want to build a team for 4vs4 Battle Spot Doubles and plan on using a Mega Kangaskhan|Volcarona combo, but am not sure on Volcaronas EV spread.
Kangaskhan (F) @ Kangaskhanite
Ability: Scrappy
EVs: 4 HP / 252 Atk / 252 Spd
Adamant Nature
- Double Edge
- Sucker Punch
- Power-Up Punch
- Fake Out
Volcarona (F) @ Sitrus Berry
Ability: Flame Body
EVs: ???
Modest Nature
- Bug Buzz
- Heat Wave
- Rage Powder
- Protect
Question: What are important defensive/speed EV benchmarks for a Modest Volcarona in this metagame?
The problem with volcarona in the ORAS metagame is that it doesn't have a very good matchup with many of the new threats, particularly Mega Salamence (resists both of volca's STABs and has SE aerilate return/double edge/thrash to hit with). Its lackluster defensive stat and typing holds it back from checking the large number of physical attackers, including landorus-t, garchomp, and salamence (to name just a few).
If you're going to use volcarona, I'd recommend using an offensive quiver dance set. Mega kanga already provides useful fake out support, though maybe you might want to consider hitmontop or another wide guard user (volca in team preview tends to draw all the rock sliders).
If you're using volca because you want a rage powder user, amoonguss is generally better for rage powder support if you need that option, unless your team has a specific reason for needing volca over amoonguss. Even then, I'd consider togekiss as a follow me user over volcarona tbh, but that's just me.
Also, you might want to use jolly nature over adamant nature on that mega kanga. Yes, this meta is getting faster so the speed won't matter as much, but you'll still want to at least guarantee a speed tie with other base 100's.
