Overload reduces the amount of mana you have available during your next turn by the number stated in order to use the current card. This ability is exclusive to the shaman class. Unbound Elemental and Tunnel Trogg are empowered by Overload cards. Lava Shock and Eternal Sentinel unlocks your Overloaded mana crystals. Snowfury Giant costs less for each Overloaded mana crystal during a game.

Below is a list of all cards with the overload mechanic.
