Black Panther justice against ultron 4 player

Ultron is not heavy on side schemes, so Multitasking will rarely get you 4: you are better off with more Impede or switching to Clear the Area.

I would also drop Beat Cop, 1 Crisis Averted, both Power of Justice, for 1 Team-Building Exercise which will bring you down to 40 cards.

@celrici understand most of your suggest, but why drop Beat Cop ? Is it not good? And i always wondering the importance of being 40 decks against ultron, since he will discard the deck. any way thx for your comment.

@MathewCCorrect. If you don't have your 1 Copy of Beat Cop in play at the end of turn 2, you are probably better off playing an ally or upgrade instead for the rest of the game.
