This build capitalizes on the aerial synergies wherever possible. The allies are all aerial, aside from his signature ally.

Six of his protection cards are aerial as well. Aerial Intervention, although not impressive on first glance, takes advantage of his healthy number of aerial allies, and allows him to play aerial cards on the enemy's turn. This allows for card draw in the enemy phase, if he is in Angel form.

Thwarting is managed by his signature suit of cards and Ever Vigilant. Furthermore, the Aerial Interventions reduce his need to exhaust to defend, meaning a greater likelihood of two thwart actions available in Angel form courtesy of Techno-Organic Wings.

His alter-ego form enables some key synergies. Worthington Industries is especially effective in alter-ego, and because the remaining deck signature-density is (or at least should be) ever increasing due to this action, Weapon X becomes more efficient in that it will reduce the number of cards discarded on average. Metamorphosis down to alter-ego then draw a card, draw another card from Worthington Industries, another from Weapon X, then flip back to hero form drawing another from Moira MacTaggert. This is just one example of the flexibility on offer here.

Resources are extensive, with two Team-Building Exercise specifically tailored to permit two aerial event cards each turn. Once up and running, play an aerial event and get the corresponding hero benefit, then flip hero forms and play another event to get the other benefit. This type of play will be efficient and allow for highly productive turns.

His survivability is very strong, as Aerial Intervention, Render Medical Aid, The Night Nurse, and Armored Vest all serve this purpose.
