To bring this topic back a little: a while back someone posted a list of viable and unviable spikers (both ou and uu). Which kind of made me wonder: what about Glalie?
I mean, sure, it's no way as bulky as most spikers are - although flat 80/80/80 defences leave it without gaping openings like with Skarmory or Forretress. Also, its typing is BAD with a big B in the bonnet. But... Let's consider the meta. With a certain magnetic a-hole running rampant, both Skarmory and Forretress struggle tu put up more than one layer of spikes without getting caught and obliterated. Along comes this little snowball, which doesn't give a damn. It might actually throw up a respectable EQ in its own right, which paired with amazing offensive Ice coverage might force quite a few switches. Let's say a set like this:
Spikes
Earthquake
Ice Beam
Explosion
With a 252 HP/252 Def (or maybe a couple of points thrown into Spd to outrun some threats) it should be quite capable of taking a hit or two from the physical side and still do its thing - set up a layer or two and take a threat down with it. I thought of this set as a kind of suicide lead, what do you think?
