Does Defy work against Sky Splitter when Sky Splitter's cost is reduced by a high Might unit?

Ruling: Defy can negate Sky Splitter regardless of cost reductions. Effects that check a card's cost always use its base cost, even if that cost is altered or ignored as the card is played.

Nuances:

• Sky Splitter normally costs 8 and can be reduced by your highest Might
• Defy only looks at the base cost (8), not the reduced cost
• Cost reductions don't change what Defy can target
