I've been using this fucker since the beginning of time and since Nintendo doesn't know how to fucking server I decided to breed a new one.

Problem is I suck at EV spreads because I don't know what can and cannot beat it with the wrong or right amount of EVs.

I know /vp/ aren't all Pokemon experts but I'm sure some of you can help.

Is there anything that can be a HUGE threat to Mega Venusaur if I don't put in the right EVs in a stat?

Also, the moves:
>Sleep Powder
>Giga Drain
>Sludge Bomb/Earthquake
>Synthesis
