useless UR card. eg: Blue-eyes or high lv monster.... Make sure you set this card before your opponent summons.
But opponent can change it back to attack position with card effect, or use as tribute / fusion material.
It's good vs silent magician/horus and all others and you can't CV while Blue-eyes is face-down and people can just soul exchange or do something funny to your blue-eyes. If it works with any case Konami will not take it in.
