Can you use Defy on Falling Star, which costs less than 4 memory but requires 2 recycled runes?

Ruling: No, you cannot use Defy on Falling Star. A card must meet both conditions (no more than 4 memory AND no more than 1 recycled rune) to be eligible for Defy.

Nuances:

• The use of "and" means both requirements must be satisfied, not just one
• Falling Star meets the memory requirement but fails the recycled rune requirement
