When ignoring the cost of a card, what costs must be paid, can be paid, or are ignored? Specifically for cards with additional costs (Accelerate, Clockwork Keeper, Cruel Patron, Meditation, Brazen Buccaneer, Kraken Hunter) and Deflect X.

Ruling: When ignoring the cost of a card, you only ignore the base cost (both energy and power). You must pay additional costs and may pay optional costs.

Nuances:

• Base cost includes both energy and power costs
• Additional costs (like those on Accelerate, Clockwork Keeper, Cruel Patron, etc.) must still be paid
• Optional costs may be paid at the player's choice
