Origin Information
Agustinia is a sauropod from Early Cretaceous South America. It is believed to have reached a length of 50 feet. While it is not uncommon for sauropods to have been found with body armor, Agustinia's armor is unique. It had a series of wide, vertical spikes and plates down the center of its back.

Using Agustinia
Agustinia is a very versatile card. Due to its large amount of HP, and the chance it will gain a somewhat defensive ability, it can be used as a way to absorb blows from the opponent's cards. However, it is more than capable of dishing out damage, especially if it has been turned into an Earth attribute

Defending Against Agustinia
To defend against Agustinia, you must simply overpower it. You'll a card capable of dealing lots of damage to minimize the amount of damage Agustinia does. Also, due to the fact it can become Earth attributed, any card that is immune to the attacks of Earth attributes would nullify its attack bonus (Not to mention it would just nullify its attack altogether)
