Amazing, underrated card for anyone who evades. Looking at you Wendy, Finn, Rita, Silas, and Stella.
The power of this card isn't in coping with powerful enemies, it's in nerfing the encounter deck. Every turn you might endure unknown horrors, and the next encounter card could be truly awful.
When you run across some mook like a spoiler or a spoiler you evade because that's what you always try. You don't always succeed because, well, this is Arkham Horror.
This card turns a failure into a grand slam: put it right back on top of the encounter pile. It follows in the style of "Look what I found!", but for enemies.
You've guaranteed that the next encounter is just another mook that you know exactly how to handle. It's like mirror of recursion from an player's draw pile: instead of recycling good investigator cards, use this to recycle milquetoast enemies.
10/10, would evade that again.
PS: For a truly cool evasion deck run both this and Dumb Luck (2), so you have the option of burying a tough enemy in addition to recurring a mook.
