A Pokemon I haven't used since the Home metawhat are optimal spreads for 'demon mew' (cosmic / stored power / body press / roost)?
I've seen multiple variants of it. The one currently listed on the Matchmaking thread looks like this:
Mew @ Leftovers
Ability: Synchronize
EVs: 252 HP / 4 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Cosmic Power
- Stored Power
- Body Press
- Roost
But I've also seen variants that run a good chunk of defensive investment with a little speed. (I can't for the life of me remember why though, I checked the speed tiers and those variants don't seem to hit any notable benchmarks. Maybe the Defense EVs secure a 2HKO on Heatran at +1 or something?)
Honestly, this Mew is pretty malleable and you can experiment with it to see which EV spreads suit your purposes best, but if you don't have any set goals in mind, 252/4/252+ should serve you well.
