Can Cithria of Cloudfield's buff be used to pay for Kraken Hunter's power cost when playing Kraken Hunter?

Ruling: No, Cithria's buff cannot be used to pay for Kraken Hunter's power cost. Kraken Hunter's power requirement is a cost that must be paid before the card is played, while Cithria's "when you play" trigger doesn't happen until after Kraken Hunter is played.

Sequence:

• Kraken Hunter's power cost must be paid first ("as you play me")
• After Kraken Hunter is played, Cithria's trigger resolves ("when you play")
• The buff from Cithria comes too late to pay for Kraken Hunter's cost

Nuances:

• If Cithria already has a buff before playing Kraken Hunter, that existing buff can be spent to pay for Kraken Hunter's cost, and then Kraken Hunter will give Cithria another buff when it enters play
• Cards with costs cannot benefit from Cithria's buff for those costs, but cards that remove buffs at resolution (like Wildclaw Shaman) can stack beneficially with Cithria
