Centaur is a neutral beta card with lots of advantages and use cases. Despite this card takes 4 mana l don't think that it's a cost-effective card because there are range attack monsters which cost just 3 mana and better than this card but take into consideration it's a neutral card which you can use it with every team and he also have snipe ability which is a helpful ability. Pros of this card are : enough high speed to evade enemy attacks, snipe ability to eliminate tanks, normal range attack and health, can be used with any team. The only con of this card is the fact that it cost 4 mana which is not a serious disadvantage.
