Yep. You are playing it right, and it isn't the most efficient hero in the slightest. If you can successfully get traps out, they are pretty interesting.....but not very understandable at first glance for some.
In rewatching the Slaughterfield video, Keith plays the Trickster starting with green items, and that seems to be making a hell of a difference for him. I'm not real keen on heroes being highly dependent on gear to make their core functionality viable.
One thing I noticed was at the beginning of a HC, the Trickster has an ability on one of his starting items that lets him roll a FD, and on a result of his symbol, he gets to search his discard pile for a part of his choice. If I remember correctly, the starting card only lets you roll 1 FD for this. With green gear (which I haven't seen the Trickster's green gear), he was rolling around 6 FD for this same check. That seems like a drastic change between starting gear and green gear.
