Fixing Decks with Exile cards is something I rather like doing, the few times it comes up it feels like cheating the system, spending 1xp to swap in a level 0 card you forgot sucks, but spending 1xp on flare and getting the swap for free is a good time all round.
Burn after reading removes two cards from your deck for 1xp and gives you testless clue gathering, it also allows something more interesting, the removal of high level cards, i don't think I have ever even considered swapping an XP card out for another one, I generally just ride it out even if the card seems to be close to worthless, but now you get to remove an XP card in your deck in exchange for the most powerful effect in the game, doom removal.
I think in a Deja Vu deck this card in a no brainer for easy clues and effectively adaptable (more than what Deja Vu already allows), if you have two Deja Vu's you could even run two of these and use them every game for 2 extra rounds and free clues, which may be worth the steep asking price. (12xp for the combo and another 4xp forany two level 2 cards)
As someone who adores gold pocket watch at its extreme cost I see myself having a lot of weird experimental fun with this.
