If you flip Karma + another card from Rek'sai's Legend effect and play Karma, does Karma's buff trigger immediately?

Ruling: No, Karma does not buff immediately. Karma is played to the chain as pending while Rek'sai's effect is still resolving, and only finalizes after Rek'sai's effect completes.

Sequence:

• Rek'sai's Legend effect reveals cards
• You choose to play Karma, which goes to the chain as pending
• Rek'sai's effect finishes resolving (recycling remaining cards)
• Karma finalizes and its buff triggers
