The worst Afterimage is ever going to be is "okay". On my second run of Slay the Spire 2 I got 130 of them from a cloning event and completely broke the game. Stuff like that is the potential upside. Goes extremely well with Shivs, or with card draw builds built around Sly, but is also surprisingly okay with slower Poison builds, since even a little bit of extra block is worth a lot for those.
