Does Grinning Trickster's rightmost Growth Option just use the Card Plays revealed on the Presence Track, or does it include modifiers (e.g., "Back Against the Wall," or Invader benefit 4 in Powers Long Forgotten)?
The printed number on the Plays track. Effects that scale via the Energy/Plays/Elements on Presence tracks use the printed amounts rather than the amount of Energy, Plays, or Elements actually usable during a given Spirit Phase, unless they explicitly say otherwise.
