I think I don't understand the Young Forest Spirit. The text says, "Discard a card from your hand and summon another card for free". Here's the situation. I have zero cards in my area, four cards in my hand, and it is round 3. I summon Firefox and gain three points for now having three cards in my hand. I then summon Young Forest Spirit and I discard Ifrit thinking I can now play Leviathan for free. But I don't get that option. I'm left with "Choose an Action" with only an Undo button and nothing else to click on. There's something I'm not getting?

Does Leviathan have an immediate effect that cannot be executed in your situation?

Thank you and yes. Now I see someone else needs a purple card to discard. Sorry about misunderstanding that.

Someone else or yourself ned to discard a purple card because of the Leviathan effect.
I once stumbled myself over this or a similiar situation.
