After you commit Copycat to a skill test, search the discard pile of another investigator for a skill you can commit to this test, and commit it. After this test ends, place that card on the bottom of its owner's deck.
This card has interesting applications in supporting a teammate, as you are not limited to committing it to your own tests. An investigator’s deck typically has more skills suited to their own specialty than someone else’s. This means you can help out your guardian pal with their own Vicious Blow, recommit a seeker’s Deduction to their next investigation or even fill out a fellow rogue’s poker hand if one of their Aces ended up in the discard.
This seems like a really good card for winifred. +2 minimum, you get to draw a card and can get this one back. Yeah for a few rounds this probably wont be good at the start but once cards like steadfast or unexpected courage are played this really develops quick.
