Can Kaisa's Legend ability be used to pay for Deflect?

Ruling: Yes, Kaisa's Legend ability can be used to pay for Deflect, but only when the spell itself is targeting. It cannot be used to pay for Deflect when the target comes from reflexive triggers (like Icathian Rain or Falling Star).

Nuances:

• The ability works when a spell is targeting
• The ability does NOT work when the targeting comes from reflexive triggers (examples: Icathian Rain, Falling Star)
