If I play Get Excited and discard Sky Splitter while Kadregrin is on base, does Get Excited deal 0 damage (due to Kadregrin's cost reduction) or 8 damage (Sky Splitter's printed cost)?

Ruling: Get Excited deals 8 damage. When effects reference a card's cost, they always reference the printed value on the card, not any modified cost from other effects.

Nuances:

• Kadregrin's cost reduction only applies when casting the card into play, not when the card's cost is referenced by other effects
• The card is discarded before it would actually be cast, so the cost reduction never applies
