Scroll down to the Supporters to see it.

"Switch 1 of your opponent's Benched Pokémon with his or her Active Pokémon."

So I suppose this means most players will take out their 2 or 3 Pokemon Catchers and replace them with this. I'd say this card alone means Trevenant will make less of an impact than Gothitelle did, even though it is a Stage 1.

Depends. It takes up your supporter slot for the turn, which cuts you out of Juniper/Sycamore, Team Flare Grunt, Colress, Bianca, etc. I think it will depend more on meta choice. If you see lots of Trevenant in your area, then yes, he'll be the Catcher replacement, but if not, I don't think he'll warrant more than two slots just because of his speed.
