If it hits, it's a card that thins down your deck and sometimes offers the utility of even choosing between multiple attack cards for the most relevant one. Otherwise you've just wasted a resource that could have paid for another card. Not sure I'd trust always hitting an attack event when looking at just 4 cards, but for a hero that is happy to swap into AE form fairly often (She-Hulk, Ms Marvel, Groot) it seems like a good effect for 0.
especially good with Ms. Marvel, you can thin the deck really fast with this + Bruno

								I've found the density of Attack events you need in your deck for this to hit consistently is just too high. Only in dedicated Fluid Motion deck or a mono-red No Quarter deck have I considered this card

								Gamora decks loaded with attack or her Cross counter is the perfect use for Plan of Attack
