Rulings

A creature with a shield counter on it may still be destroyed by state-based actions if it has damage marked on it equal to its toughness or has been dealt unpreventable damage by a source with deathtouch. — If a permanent that would be dealt damage has more than one shield counter on it, that damage is prevented and only one shield counter is removed. — If a permanent with a shield counter is dealt unpreventable damage, that damage will be dealt and a shield counter will still be removed. — Removing a shield counter when a permanent would be dealt damage or destroyed isn’t the same as regenerating a permanent. — Shield counters don’t prevent players from sacrificing permanents. — “Shield” is not an ability that permanents have and shield counters are not keyword counters. If a permanent with a shield counter loses its abilities, the shield counter will still protect it as normal.
