The key card is present but its support is thin.
Prioritize useful support such as Fortress Kin-Guard or Kin-Tree Nurturer.
Choose the Spirit from Kin-Guard or Nurturer when Tactician needs fuel. Pay one mana to sacrifice that token and draw while keeping the original creature.
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.
Tactician sacrifices tokens specifically; a spare nontoken creature is not a legal payment. Keep the mana needed for the activation.
The support is missing
Favor independently useful creatures and interaction if the narrow support does not arrive.
