Mind reading/control isn't trickery though. Trickery is a means to an end, manipulation through anticipation and deception, but if you bypass that means and jump straight to direct control, you're not a trickster. Charles Xavier is not a trickster like Coyote or Loki despite the fact that they can both make you do things and find out your secrets. With Coyote, you come away kicking yourself for not seeing through his schemes, but with Charles Xavier, you just come away feeling powerless and perhaps violated.
Intellect Devourers are not trickster mascots.
