Skeletal Warrior is a great lowest mana capped tank. In sneak mode this guy can rock also if you're battling in a game mode which high mana capped then you can use this card and another tank behind him if you don't want to use two high mana monsters. Pros of using skeletal warrior are it's a 2 mana card and you can use this card when you have 2 mana space left, he has a 3 shield at maxed out level which is too important for a low health monster, he has shield ability to protect him from melee and range attack monsters. Cons are low speed, low health and low melee attack. Best way to take down this is to use magic.
