Cool trick that I recently learned:

• Sneak a high cost ally
• Make it become defeated in that phase (by extra Get Ready or Command Team, for example)
• Trigger your Rapid Response to recur that high cost ally. Its no longer affected by Sneak Attack's end-phase effect.

Some heroes for you to consider

• Black Widow (example deck) can abuse from RR spam.
• Cyclops can also find both Sneak Attack and Rapid Response since they are TACTICs.
• Spider-Woman allways to consider because she can open to RR allies from other aspects than leadership/basic. [LIST (CLIC)]

The second best healing card in the game behind Queen Ramonda. Spider-Man likes to flip down to use Scientist, but you’ll want to make sure to have good ways to thwart when deck-building. Being able to use this card twice when flipping down naturally is awesome, you can usually heal to full when flipping down without having to recover.

A fantastic treachery cancel for 2 ER. Hanging in hero form and scared of Assault or a big attack from a villain? This card can help you and cancel a lot of nasty villain abilities. It is a bit awkward to know when to keep this card and when not too, but Spider-Man’s excellent economy really can justify keeping it in your hand. The art is very cool, Spider-Man’s spidey sense is preparing him to negate whatever the next villain is throwing his way. This card is super thematic.

If Energy Shield is already in play could this be spent to trigger its damage reductions? This card doesn't say it's to 'play' an aspect card so maybe there is some wiggle room. And now some filler text to make 200 characters.

Okay, so this is another incredible card for Wanda's kit. No question. Just straight up canceling a card play is incredibly powerful.

It does feel like it's making up for how Wanda plays though. It's not an additional bonus. It's just helping you mitigate a downside built into her kit. She moves through her deck incredibly fast. When she empties her deck, you're dealt an encounter card. Then you draw this and get to negate an encounter card. You're not really coming ahead. You're just negating the card you keep dealing yourself.

I think that might be what I appreciate the most about this card though. The designers realized at some point in development that she moves through her deck incredibly fast, dealing herself more encounter cards, and she needed a way to deal with that. So they added this to let her negate one encounter card per pass of her deck.

Edit: Removed the part about Deft Focus. I forgot you can't use Deft Focus during the villain turn.
