I would much rather it didn't do thwart, but allowed you to simply pick a minion from the deck rather than discarding until one is discarded in exchange. IMO the Justice counterpart, One Way or Another is much, much better.
Hero Action (thwart): Discard cards from the top of the encounter deck until you discard a minion. Put that minion into play engaged with you → remove 3 threat from the main scheme.
Galaxy's Most Wanted #43.
Agreed. Discarding until you find one can be quite dangerous, you might have to dig through quite a few encounter cards and that puts you much closer to another acceleration token. The thwart hardly seems worth it. Obviously works best with Thor but a bit questionable even there. — Fates · 2
