Mystic Vale: Mana Storm Expansion

From AEG:

A Card Crafting Game of Nature’s Power!

The campaign to restore Gaia's realm rages on and other druidic clans combating the curse have joined the ranks. And it’s not just druids who have heeded the call; other creatures have joined the fight, eager for a day when all are free from the accursed blight.

The Mana Storm expansion adds new advancement and vale cards to the base Mystic Vale game, giving players more card crafting options and exciting new possibilities for combos. New leader cards grant abilities that can be upgraded to become even more powerful! Amulets feature unique effects and greater variety over regular mana tokens.

You need the core game to play with this expansion.
