underdog of the year
I didn't mean to doubt that Nature Power is a decent move on Shiftry but just meant to say that I hardly ever see it (not that I see Shiftry too often, either). I suppose it is a viable option for those having issues with Absol though. x)Ground is solid coverage alongside grass, I don't see how it's that shocking. You hit poison and fire, and sucker-punch is enough to deal with much of what that doesn't cover. I didn't realize that absol commonly runs HP evs, but that's still enough damage to prevent absol from destroying your team. If it's used superpower once, it will lose regardless.
I've seen defensive mesprit use Ice Beam. Its a decent coverage move for it. Assuming 0 hp doesn't make sense, either, as between chlorophyll and sucker punch shiftry has plenty of room to invest in bulk.
Most Mesprit I run across either run something like SR / Thunder Wave / Psychic / U-turn, a Scarf set, or a CM set. Most of the time I only see Ice Beam on the CM variants; never have I seen a purely defensive one use it. Just speaking from my own experience, more or less.
