Cannot be Normal Summoned/Set. Must be Special Summoned (from your hand) by Tributing all monsters you control, and cannot be Special Summoned by other ways. This card's ATK becomes the combined original ATK of the Tributed monsters. If this card attacks a Defense Position monster, inflict piercing battle damage to your opponent.
Legendary Maju Garzett has the potential to be a very powerful beatstick but offers absolutely no self protection. This makes him an easy target for removal effects. Power of the Guardians can be used to protect him while he does what he does best.
A few high-leveled monsters can be Normal summoned without tribute but with a negative effect. Legendary Maju Garzett can use these as tribute fodder and gain their powerful attack.
