When using alternate play methods (like hook, aurora) that ignore a card's costs, do you still have to pay additional costs like sacrificing a unit or paying for accelerate?

Ruling: When using alternate play methods that ignore "its costs," you still must pay all additional costs. The phrase "ignoring its costs" only refers to the base costs (energy and power), not additional costs.

Nuances:

• Optional additional costs (like accelerate) may be chosen but must be paid for if chosen
• Mandatory additional costs must always be paid
