oath of the gatewatch booster box The expansion symbol of the set seems to be a stylized representation of Kozileks brood but it also has similarities with hedrons usual for Zendikar sets 1x Oath of the Gatewatch:

Carracosta has the following attacks: Blocking Shell - 100 damagePrevent all damage done to this Pokmon by attacks from Basic Pokmon during your opponent's next turn

This card technically comes via Avatar Eternal rather than the main set, but dont hold that against it

At the time this card was made (which was before this point in the show I think), 3200 attack points was unheard of, and due to the nature of Ritual Summons was very easy to get on the field
