Shield Dancer

Oracle Text

2W: The next time target attacking creature would deal combat damage to Shield Dancer this turn, that creature deals that damage to itself instead.

Card Rulings

10/4/2004 If the ability is used twice, it will cause the next two attacks this turn (which only happens if something gives a player two attacks) from the creature to “reflect” back to itself. It will not result in double damage back from a single attack.
