The key card is present but its support is thin.
Prioritize useful support such as Mouser Foundry or Mechanized Ninja Cavalry.
Sacrifice Foundry to a kicked Stomped by the Foot for a Robot and stronger removal. Cast Mystic afterward for another body and Raphael trigger.
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.
Do not sacrifice a creature you need to survive combat just to upgrade removal against a small target.
The support is missing
Favor independently useful creatures and interaction if the narrow support does not arrive.
