The Three Best Friends That Anyone Could Have...

The basic idea is to have 3 characters who can routinely give 3ATK/3THW every turn. It won't give you a 30 DMG turn, but it consistently moves forward. This deck only uses cards through the Guardians cycle.

Build around Captain Marvel and Daredevil. Buff them up with Team Training, Honorary Avenger, Power Gloves, and Reinforced Suit so they stick around the whole game (up to 7HP possible, with 3ATK/3THW each, plus 1 damage with Power Gloves). CM draws a card for you for any activation, and DD pings some damage after thwarting. Use First Aid and Inspiring Presence to heal them. Note that Daredevil needs Honorary Avenger to wield Power Gloves.

Use Call for Aid to find Captain Marvel quickly. If Daredevil is discarded as a result, there is one copy of Make the Call to bring him back (unless it was also discarded). You can also use a 2nd Call for Aid after CM is on the table to burn through your deck and start over. You might even consider this after both allies are on the table to bring back to some strong Spider-Woman cards (e.g. Pheromones, Venom Blast, Contaminant Immunity) or First Aid more quickly.
