The key card is present but its support is thin.
Prioritize useful support such as Mob Lookout or Whoosh!.
Attack with Spider-Gwen to discard Bolt, then cast Bolt in the second main phase. A later Lookout provides another discard outlet.
Your deck already enables the plan but is losing the early turns.
Take a castable early creature or efficient answer before a second expensive payoff.
Blue bounce buys time but does not permanently answer the threat. Use the tempo window to deal damage or develop another creature.
The support is missing
Favor independently useful creatures and interaction if the narrow support does not arrive.
