With the release of Standard 2 and Expert 2, I feel that this is a card that most decks should be considering as a 1x or even a 2x. Many of the new boost abilities lead to additional boost cards being drawn and things can spiral out of control. This is capable of stopping the problems before they start.
A very scenario-dependent card, but agreed it is very powerful when needed. I recall some of the GMW mod sets having minions that come in to play off boost. This is a cheap way to beat a whole minion!

								There are some scenarios where on Expert, I just pull all three out and say, "okay team, I don't care if it means running a 41 card deck, but everyone is going to do their part on the team and run a copy of this."

								@death by chocolate  Agreed! Even before Standard 2 / expert 2 some villains have nasty boosts... Klaw comes to mind with sometimes two nasty boost effects on a single attack! And not to mention GMW...

								@neothechosen Yup! Sometimes you just can't afford to let Star Shark or Under Attack kill five allies!

								Just a question, it doesn't cancel the boost icons right?

								Correct, Target Acquired will not cancel boost icons

								That is an important distinction beacuse there are multiple encounter cards that have both both types of boost (Star/Ability & Triangle/Boost Icon).

								Another comment is that this is a Hero Response, so you may get unlucky and be unable to trigger this response if you flipped down
