Long Live Hawkeye

Deck is designed to keep Hawkeye out in Hero mode as long as possible despite his terrible Defense. Most cards are cheap and you are meant to take advantage of his arrows as much as possible. Standard Avengers Mansion and Helicarrier if you have the resources. Brother Voodoo has synergy hunting for additional arrows. Iron Fist is too good not to include. Plus, works if you really want to get extra damage off Electric Arrow. All the other cards focus on healing or preventing damage, and can even deal it too. That combined with cheap arrows and three Attack from Hawkeye's Bow you’ll be dishing out the damage.
