Raining cats sounds like a good thing! I guess the shape of the card tells those who know what type of card it is? So far I've heard people mention spells, towers, and heroes.

What does any of this have to do with Splinterlands though (apart from this game apparently wanting your hard earned SPS, like everrybody else.) Can you use those cards in SPL battles? Put them to work on land on in those magic wagons? Or vice versa, can your Grund and Tarsa go play among the towers?
