The Vision Needs to Make the Call for the Avengers' Aid

This deck revolves around using Squared off to put allies into play cheaply through Squared Off. Depending on the minion that comes into play, Vision may be able to ignore it while he's Intangible. That or he can try to kill it with allies or events. Vision can usually handle all your thwarting needs through basic thwart, Just Passing Through, and Solar Beam. After your board has been built with resource generators, Density Control, and Vivian, you'll probably start switching to Dense and start wailing on the villain.

Squared Off can be annoying if you don't have an ally in hand. Therefore, we have Call for Aid to find an Avenger (which is the only kind of ally added the deck). Do note that Vivian is not an Avenger, but you can still get her through 616 Hickory Branch Lane or Make the Call. Alternatively, if you put Black Panther in play, you can store a copy of Squared Off until you have an ally. Though, sometimes you'll want to store a Make the Call or a Squared Off if you play him from hand or via Make the Call. It will just depend on what allies and events are in your deck and discard pile.

War Machine is to help you switch dense form or if you anticipate a big hit from the villain. Giant-Man helps to do some damage. Kaluu can help you find sweet Vision events or others you may need (ie Squared Off if you have Call for Aid or vice versa). White Tiger can draw you cards without having to pay her cost via Squared Off. The two Reinforced Suit is to help you give your allies some longevity to do damage while you tank hits in Intangible. I particularly like it with Vivian because I don't like to flip to alter-ego to recur her. It also keeps her in play longer for you to draw Reboot.

Face the Past could go in the deck as he can just tank Ultron's damage. It might help setup a little quicker or align an ally/Call for Aid with Squared Off. I'd consider replacing it with either a Call for Aid or Reinforced Suit.
