How does Portal Rescue work with units that have Accelerate, specifically regarding power costs and accelerate costs?

Ruling: When playing a unit with Portal Rescue, you ignore the unit's base Energy and Power costs, but you must still pay the Accelerate cost if you want to use the Accelerate ability.

Nuances:

• Accelerate is treated as an Additional Cost that is not ignored by Portal Rescue
• Only the base Energy and Power costs are ignored when playing the unit via Portal Rescue
