Cocatrice is a unique neutral monster with lots of use cases. Though it takes lots of money to max out this card he can help you to win lots of matches in different game modes especially sneak mode. Advantages of playing with this card are this card costs just 2 mana where if you have 2 mana space left then you can use it, high speed, flying ability and dodge ability helps him to evade melee and range attacks. Best use cases in my opinion are where all melee monsters have sneak an, melee monsters can attack from any position etc. Disadvantages of this card are low health and low melee attack.
