When playing a card with an effect that ignores its cost (like Dazzling), do you still have to pay additional costs like Accelerate? Does 'ignoring' count as cost reduction?

Ruling: Ignoring a card's cost only applies to its base (printed) cost, not additional costs. You are never forced to pay additional costs, but you can choose to pay them. Cost reduction effects can reduce additional costs to 0, allowing you to 'pay' them without expenditure.

Sequence:

• Ignore base cost where applicable
• Apply additional costs
• Apply cost increases
• Apply discounts in any order

Nuances:

• 'Ignoring cost' and 'cost reduction' are different mechanics - ignoring only affects base cost, while reduction can affect additional costs
• If an additional cost is reduced to 0 by any means, you can pay it with no expenditure from your rune pool
• If an additional cost isn't paid, you won't get any effects dependent on it
