the gameplay is progressing sort of as a mixture between MtG and Pokemon. At this point, most spells are more like trainer cards in Pokemon than like spells in MtG (meaning that while they still require energy like MtG's mana, they can be played by anyone regardless of elemental affiliation like Trainer cards in Pokemon).
So as it stands, right now this card can be played by anyone for (3) energy. If I decide to make it aligned with an element, it will probably be Fire or Water. We'll see how well I can mix the two types of games. It might make the different elements not different enough from each other, which would get boring imho.
We're playtesting with real cards, using stickers to put them on the front of face cards )).
