Can Kaisa's ability be used to pay the power requirement of spells, and can tapped runes be used to pay recycle costs?

Ruling: Kaisa's ability generates power (not energy) which can be used to pay for a spell's power requirement. You still need to recycle the required number of runes for the spell's recycle cost. Tapped runes can be used to pay recycle costs.

Sequence:

• Recycle the required number of runes for the spell (can be tapped or untapped)
• Use Kaisa's power generation to fulfill the power requirement
• Example: For Smoke Screen, recycle 2 runes and tap Kaisa to pay for the power

Nuances:

• Kaisa generates power, not energy
• The recycle cost (number of runes) must still be paid separately from the power requirement
