After running Michael McGlen with this card for 6 scenarios I have a lot of positive things to say.
It's a Lv. 0 Rogue card with the same vibe as "You handle this one!", as in you can hold it in your hand like Lucky! and be smug about tests you are going to perform.
Actually I like this even more because if resources are available it can appear like you just spend some resources to "cancel" the treachery, it is not going to anyone else. Now look at Counterespionage with 1 XP, 2 play cost, that you even have to draw a new one if you choose not to pay more! Now Rogue can just happily eat up the fixed 2 horror kind of treachery. For the fail by kind, maybe you actually passed and not having to play, maybe you get fail by something for just 1 and not play this card.
Michael I'm testing this with comes with 3 and 3 which goes well with this card. A lot of time I'm so ready to play this card then draws a 0 or -1 which gets him minor punishment, then I can decide to keep it! Compared with Mystic using Ward of Protection in fear of getting maximum fail-by (and have to take 1 horror anyway), this is much better, you can do this with your nearby friends. Now imagine Wendy Adams with 4 and 4 holding this card, and Lucky!, with her token redraw ability.
It felt Guardian-ish with its area effect. It can cancel out location entry hazards if your friend just went ahead from where you are, back-of-agenda flipping effects, any personal issues on signature weakness, and even horror on deck resets. Compared with similar Deny Existence, that ironically felt more Rogue-ish because the cancellation is self-centered. This card can also cancel both damage and horror in one go. For references, the actual Guardian cards that guards their friends like Heroic Rescue, "Let me handle this!", Bestow Resolve, First Watch, "Fool me once..." are more proactive and aren't working with the test's result (reactive) like this one. The resource they have to spend is a bit tricky if you are playing closed information in your table, though sometimes they caught on this card is in my hand when I simply ask them to have some spare resources and not moving away too far from me. Late game Seeker usually is overflowing with resources.
As cherry on top, it gives that you can add on top of Manual Dexterity for high impact tests, make your 3 friends able to evade on their own, and even one that maybe useful for cases when this card can't cover like getting up from Frozen in Fear. It looks unusually generous, looking at other reactive hoard-in-hand card like Lucky! with no icons, or Ward of Protection / Deny Existence with a single icon.
Lastly this is likely be included the 2026 Current Environment, it'll be a staple for new generation player's Rogue for years to come. If Revised Core Set is unchanged, great for both Skids and Wendy. Good card!
