Drifblim never really survives for long which is why I love to use Destiny Bond on it. You're usually going to be able to take a Pokemon down unless Drifblim somehow dies to residual damage like Toxic. The trouble with Drifblim is that it's hard to get it in safely especially since it's weak to Stealth Rock; it is also slower than most Pokemon on offensive teams before Unburden is activated. Electric-types will usually wall it as well, but Drifblim can take them down with Destiny Bond. However, I'm not sure if Drifblim is really worth using just to take down a Pokemon with Destiny Bond, which is what Drifblim is best at. Most of the time, there are various other Pokemon that can probably fit your team better than Drifblim. If you're dead-set on luring and taking out a certain threat though, I wouldn't ignore Drifblim. It's best used as Molk described. I would consider Drifblim viable in this metagame.
On a side note, I'd appreciate it if you guys also discussed whether or not a Pokemon is worth using or not (or viable / not viable). I was thinking of color coding the Pokemon in the OP so people know the better threats!
