If I hide a Consult the Past, then reveal this card on my next turn, can I then play Jhin, Meticulous Killer for its alternative cost of 1 blue power?

Question

Accepted Answer

Yes, you can. According to **RiftJudge FAQ #10012** and **FAQ #9920**, Jhin, Meticulous Killer's alternative cost requirement is satisfied if you spent 4 or more energy to play a spell this turn, regardless of whether that spell resolved.

However, there is a critical distinction in your scenario:

### The Ruling
When you play **Consult the Past** from its **Hidden** state, you are playing it for its Hidden keyword cost, which is **0 energy** (as per **RiftJudge FAQ #9255**, you paid the 1 Power cost to hide it, but the cost to play it from hidden is 0 energy).

*   **If you play *Consult the Past* from Hidden:** You have spent **0 energy** on a spell. This **does not** satisfy Jhin's requirement of spending 4 energy.
*   **If you play *Consult the Past* normally:** If you instead chose to pay its full energy cost of 4 from your hand (as permitted by Rule 811.3), you would satisfy Jhin's requirement.

### Summary of the Requirements
To use Jhin, Meticulous Killer's alternative cost of 1 Power ([C]), you must spend a total of 4 or more energy to play a spell during the current turn. Because playing a card from its **Hidden** state specifically ignores its base energy cost (making it 0), it will not contribute to the 4-energy threshold required by Jhin.

**Therefore:** If you play *Consult the Past* from Hidden, you cannot play Jhin for 1 Power. If you play *Consult the Past* from your hand for its full cost of 4 energy, you can then play Jhin for 1 Power.
