So, this just came up while I am playing my first 2 spirit solo game.
I goofed and Ocean doesn't have the energy to pay for both the cards I want to play this turn, however, River is going to be playing a card to give Ocean energy this turn. As I can determine the order and both things are fast, I can gain the energy before I activate the card.
My question, is that a legal move? Can you play a card you cannot afford if you will gain the energy to use it before the card activates? And, if you do play such a card, but something happens and you cannot gain the energy, what happens?
My understanding is that you have to assign the energy when you play the cards, but is this incorrect?
