Escaped Shapeshifter

As long as an opponent controls a creature with flying (This creature can't be blocked except by creatures with flying.) not named Escaped Shapeshifter, Escaped Shapeshifter has flying (This creature can't be blocked except by creatures with flying.). The same is true for first strike (This creature deals combat damage before creatures without first strike.), trample (If this creature would deal enough combat damage to its blockers to destroy them, you may have it deal the rest of its damage to defending player.), and protection from any color.
