Blindfold is an interesting ally that is quite good in X-men decks and fringe playable elsewhere. Thanks to the X-men support cards like Utopia and Danger Room, the bar is quite low for any X-men ally to make the cut in a dedicated X-men deck. Her ability is hard to quantify relative to other game actions but clearly powerful. You need to be mindful of what encounter cards will be drawn as boosts or as encounter cards, and how that changes when you remove a card, but it is a good way to delete a devastating boost effect or a card like Shadow of the Past. It can also help you decide whether you should enter the villain phase in alter ego or hero form, and whether you should tank or block the villain's attack. For example, if you are 3 threat away from completing the main scheme, but you know the villain's activation will only put 2 threat on, you can safely end your turn in alter-ego to get the extra hand size. On the other hand, you could be sure to end in hero form if you know a scheme would lose you the game. One thing I like is you can get all the value out of Blindfold in one turn cycle with a play-activate-block and clear up the ally slot right away, or you can put a Mission Training on and get lots of value over time. Shout-out to Wiccan as well, who always likes to know what's on top of the deck. Blindfold is an easy inclusion for any X-men deck, and with such a unique ability could be a role-player when fighting certain scenarios.
