In the past week or so since MEV was released, some tricky smart players figured out an infinite combo utilizing a combination of Black Box and Techno-Organic Virus. Today, UDE (ie: "The" Ben Seck) posted an errata of the card's text up on the VSRealms.com forums.
The card now reads: "Shuffle up to three target cards not named Black Box from a single player's KO'd pile into his deck. If you control an X-Force character, draw a card."
I think this is an elegant solution that still makes the card playable without ruining the usefulness of a good card. Thanks TBS!
And now back to your regularly scheduled gaming. :D
