At the end of combat, destroy all non-wall creatures blocking or blocked by Basilisk. Moss-covered statues littered the area, a macabre monument to Basilisk's power. The Fourth Edition version of this card will never destroy a Wall, while the Limited, Unlimited and Revised edition versions will destroy an attacking wall which the Basilisk blocks.
Creatures can regenerate from the Basilisk's power.
The effect is added to a creature which becomes a blocker by any means, including being part of a band which is blocked or by being moved into blocking or being blocked by an effect such as General Jarkeld . This effect stays even if the creature is removed from the blocking situation by an ability like General Jarkeld . Protection from Green does not prevent the Basilisk's power because the ability is not a targeted effect. See Rule G.42.Ruling.1. This means that a creature may have to regenerate twice to survive the combat, once from damage and once again at end of combat.
