What EVs and item should I use on this Naganadel set?

I have a lvl. 21 Poipole in Shield and am hoping to have a Sweeper Naganadel with these stats:

Naganadel@???Ability: Beast BoostEVs: ???Hasty nature (+Speed, -Defence)-Dragon Pulse-Air Cutter-Toxic Spikes-Nasty Plot

Knowing that I want it to be able to set up with Toxic Spikes and Nasty Plot, and that Naganadel has mediocre HP, what EVs could I use to make it survive for that time and still KO a few Pokes? Item?

Please do NOT comment on the moveset (unless if it’s to say that it’s good).

Thanks!

If you are planning for a simple Special Sweeper Naganadel set,252 SpA/252 Spd/4 SpDis the way to go. It maximizes the amount of Damage output and lets you outspeed more things as well. As for the item, I would go with aLife Orbto further boost Damage output and combine that with a Nasty Plot boost, you will sweep everything that doesn’t outspeed you.I know that you said not to mention the moveset, but I would replace Toxic Spikes for Sludge Wave and Air Cutter for Flamethrower to give the ability to hit Steel types which you currently lack.
