Can Soulgorger bring back a unit ignoring its energy cost but still pay the Accelerate cost to have it enter ready?

Ruling: Yes, Soulgorger can bring back a unit ignoring its printed energy/power costs, and you can optionally pay the Accelerate cost to have the unit enter ready.

Nuances:

• Soulgorger's "ignore costs" effect only applies to the printed energy/power costs on the card
• Accelerate is a separate optional cost that can still be paid when using Soulgorger's effect
