Yondu//Black Cat infinite attack!

Quick idea : Find Black Cat or Yondu. Boost them to (non) death because attacking don't have consequential damage.

Spidy block each turn and cheer them up! Use card as Backflip, Webbed Up and Enhanced Spider-Sense to gain Time for installing/improving the combo. Drawing allies help you dig deeper in your deck. Try to keep Spiderman in hero form because this deck is not gear to handle thwart. Spider Sense (Spidy’s ability) let you dig deeper into your deck.

If no Cat or Yondu in starting hand, mulligan it!

Untap power like Command Team and Sky Cycle help you abuse the combo.

Honorary Avenger let you play the Avenger boost card and give your ally a health buff for resisting to some encounter cards or let you thwart with allies without killing them.
