[RATE MY TEAM] My first ever VGC team

[Eckley]

Okay, so I've changed Rotom's EVs to 252 HP / 116 Def / 100 SpA / 40 SpD which survives Neural Sp.Attack natured Rotom-W Hydro Pump with up to 112 EVs in Sp.Attack. when the rain isn't up. It's a 52% chance to be 2HKO'd by Adamant 252 attack waterfall from azumarill, and it's a 50% chance to be OHKO'd by adamant 252 Attack waterfall from M Swampert with no rain. Adamant 252 Attack Landorus-T's Rock slide does 56-66.2% and Jolly Life orb rock slide from Garchomp does 61.1%-72.6%.

I've gone for a defensive variant to survive physical attackers and hopefully get a burn on them. I thought this would be better than trying to survive water type attacks, since I'm running a rain team, and if the rain is still up, rotom is going to get OHKO'd by a water attack anyway

Is this spread ok?

Edit: I think I calced these in singles, so in doubles, wouldn't the rock slides be doing less?
