The Rise of Red Skull #47.
Skilled Investigator

Solid card. You replace it with the first use and a it is a great target when a treachery forces you to discard an upgrade because it's 0 cost. You can have additional copies to maximize your chances of drawing and because you can play them under another's player control in multiplayer.

Any reason this card wouldn’t work with player side schemes? — Melosh007 · 1

I almost never play a justice deck without at least one copy of this card. Against villains with plenty of side schemes like Red Skull I'd say it's a no-brainer to have a copy for every single player in your deck (obviously limited by 3). Zero costs make this card additionally attractive, so picking it or not is basically just a question of opportunity costs (and at least right now I don't see 25 better cards in case of heavy-side-scheme-villains).
