I'm done my first-ever custom EV spread for Mega Manectric, and I'm really happy with it. However, I've accomplished all of my goals, and I have a total of 84 spare EVs and I'm not sure where to put them. Here's what I've got so far, along with a brief explanation.
EVs: 252 SpA / 60 Def / 12 HP / 100 Spe / 84 extra
0 IVs in Attack
- Volt Switch
252 SpA lets me dent Suicune and Milotic, as well as take ~70-90% off of Mega Charizard Y. HP and Defence EVs allow me to survive +1 Sucker Punch from Bisharp, as well as a few other notable things. The Speed EVs are there to outspeed Jolly 252 Spe Mega Kangaskhan.
So, my dilemma is: do I put the 84 spare EVs into HP, to tank some random hits, or Speed, to outspeed random stuff and some of the slower Choice Scarf users? This is for use in VGC 2015 format, so 4-of-6 Pokémon, Double Battles.
