And that's not even factoring in the potential Stealth Rock/Spikes the opponent may also have up.
Simply put, in order for Dugtrio to come in the 2HKO Clefable it's gotta sacrifice a good deal of it's Speed or Attack EV's, which in the grand scheme of things, defeats the purpose of using Dugtrio in the first place.
Mind you Choice Scarf variants still take 73.46%-86.26% if they invest 128 EV's in Sp Def, so there goes that as well.
