Most Scarfers get OHKOd by Sub Gastly anyway - it should really run Hypnosis if it wants to beat Munchlax 84% of the time (assuming it Subs on the switch). Burning Lax does nothing - if you want to sack yourself to kill it, use Explosion. Duskull is better at crippling Ghost counters with WoW. The difference is that Ghost-counters like Munchlax and Stunky can actually trap Ghosts with Pursuit, which Grimer can't do - if I think you're going to SS my Gastly I'll just go to my Bronzor or Gligar. Of course, this ignores the fact that Duskull easily burns you. The other Ghost counters have much better utility as well - unSTABbed Shadow Sneak from Grimer isn't going to dent many sweepers, while Stunky's Sucker Punch will help you check threats. Meanwhile, Lax is an absurdly good counter to many specially-based pokes and it hits much harder than both to compensate for its lack of Explosion. This looks pretty good, actually - I'd quite like to try it out at some point. How much does it take from Snover's Ice Shard? The only real problem is Mankey switching in - it completely screws up your momentum, as it can just U-Turn. It can keep doing that all game, as well, because it's faster and Shroomish doesn't have the moves to hurt it.
