When using Dazzling Aurora to play a card, are additional costs (like Cruel Patron's requirement to kill a friendly unit) also ignored, or must they still be paid?

Ruling: When Dazzling Aurora says to ignore costs, it only ignores the base cost of the card. Additional costs (such as Cruel Patron's requirement to kill a friendly unit) must still be paid.

Sequence:

• Dazzling Aurora ignores the base cost first
• Additional costs are applied in subsequent steps after the base cost is ignored
• If you cannot pay the additional cost (like having no friendly units to kill for Cruel Patron), the card goes back to the top of your deck and you don't get anything from Aurora

Nuances:

• Triggered abilities that occur "when played" are still triggered normally - they are separate from costs
• Effects that say "ignore costs" do not include additional costs based on the definition in the rules
• This same principle applies to other additional costs like Accelerate
