Recently we’ve decided that bundles will mostly be purchasable for real money both on PC, consoles and later in the future on iOS.
This change will help us grow the game more and create really sweet vanities in the future. Some ornaments will still be purchasable with meteorite powder.
With update 4.0 our in-game shop description of meteorite powder will read: Meteorite powder can be used to transmute standard cards into their animated, premium version. It's also used to purchase some of the ornaments - available in different shop sections.
