Black Widow endless Squirrel combo

This deck is intended for minion heavy scenarios like Ultron and Mutagen, but it works well against anything.

The premise of the deck is to use Call for Aid to fetch up Squirrel Girl. It might also hit Winter Soldier, but you have 3 tries. After you play Squirrel Girl you use Make the Call and Rapid Response to bring her back over and over again for that sweeping damage.

Eventually, with all her combo piecesin place, especially Safe House #29, you can do this every round, dealing extra sprinkles of damage along the way. The squirrel combo is so potent you don't have to worry about defeating the villain (the sweeping damage even bypasses guard minions) and can focus your other energy on thwarting and controlling.

When playing you should alternate between hero and AE every round to maximize value and card draw. Play as many permanents as possible your first time through the deck and by your second or third run your deck will be thin and powerful. Easy win.

As a final note, this deck is much better in multiplayer. Not only are there more minions in multiplayer, but if you and your teammates have the board in control then you can use the resurrection tools on Maria Hill instead, filling everyones' hands with cards. It's pretty fun either way.
