Hi folks--this is less a review than a post to point out that in the new "List of Taboos" FFG released with new Errata, Key of Ys has been "Mutated" to have the Exceptional keyword. That would mean this would cost a whopping 10xp, right? That almost certainly puts it outside of playable for most decks. That seems like a wild over-correction to me... I appreciate the List of Taboos as an incentive to keep deckbuilding fresher... but what do you all think?
I personally would be disposed to house-rule it to keep the exceptional key-word, but shift the XP to 3 or even 4 (which would total 6 or 8 xp). A 10 XP total cost just seems grossly prohibitive.
