Crypt Mancer is one of the coolest looking card added in the game. Despite the fact this legendary summoner costs 5 mana you he have additional abilities which no other rare and epic summoners have. Crypt Mancer reduces the melee attack of the all enemy monsters which makes the enemy weaker, reduces the enemy speed which is eays to hit enemy monsters and attack of the enemy monsters will be less effective. Crypto Mancer also reduces enemy health which now it'll be more easy to destroy enemy monsters. You can get this card from opening booster packs or buying it on the market.
