Or is there any?
Each form is a replay on Pokemon Showdown!. Forms of indirect damage:
Burn Poison/Bad Poison Confusion Curse Nightmare Bad Dreams Trapped (Through Wrap, Fire Spin, etc.) Leech Seed Spikes Stealth Rock Sandstorm Hail Sun (With Dry Skin/Solar Power)
So in a nutshell, Nightmare (from Bad Dreams) doesn't rely on speed. And that's it!
