"Spider Bowling" refers to the play line of playing Spider-Man into Kingpin's location on turn 5 to ensure your opponent cannot fill it on turn 6, allowing you to Aero or Juggernaut cards into Mr. Fisk's effect. With Zabu's cost reduction, we can play both Kingpin and Spider-Man in the same turn, potentially with Daredevil's information.
The lower part of the curve is about using Beast's cost reduction along with Hood or Titania to get a 0-cost high power card to pair with our late game (Professor X on the Daredevil turn backed up with 5-6 free extra power is very hard to beat).
Another fun line this deck can take - play Cloak + Kingpin in different locations on turn 5, so your opponent doesn't know which location Kingpin will end up in. Move Kingpin and catch them by surprise! (If you enjoy the coin flips of building your own New York - feel free to replace with Lizard or a tech card otherwise)
