Jadzi’s not Invoked ability reads:
“If not Invoked - When an effect you control drains mana from your opponent’s hand: Gain 7 mana.”
Kiora’s first PW ability at level 4 reads:
“Drain 6 mana from your opponent and gain 6 mana.”
Basically by using Kiora’s first with a not invoked Jadzi on the battlefield I should gain 13 mana. But that PW ability doesn’t trigger Jadzi.
On the following link you can see that I had a 9 mana cost spell as my first card in hand. The spell didn’t had any mana before I activated Kiora’s first and after I did the card only gained the 6 mana from the PW ability.
