Lord Arianthus is a reward card with lots of utilities to take advantage of. Though this card isn't good at attack but he's the hardest monster to take down. He has enough abilities to protect him from any kind of attacks. He has shield ability to protect him from range and melee attacks, void ability to protect him from magic attacks, reverse magic ability to use enemy's magic against the enemy itself. I think that this card is a must use card but I would never use this card in a game mode where all monsters lose their abilities but l always use this card in a mode where all range and magic momsters have snipe ability.
